New and Improved Shaft Chart

[golffitness23]

I was just wondering what length over standard does to the flex (inch over or half inche over standard)? Thanks,

[golffitness23]

i play my shaft 1 inch over standard and am thinking about dropping down to half inch over if it brings my ball flight and spin rates down. I currently play a matrix 7m3 XX stiff flex in my driver and it's the first shaft to drop my spin rates down to optimum levels and still launch the ball decently. I currently play 6.5 PX and they launch way to high and spin way to much to where I can't even hit knockdowns because they get up to quickly. I play to a scratch handicap as well, so i'm pretty decent golfer as well. So per my question above...will going to a stiffer and shaft and shortening the club drop my spin and launch angles theoretically? or would keeping at an inch over be fine as well. All help would be greatly appreciated otherwise i'm just going to grind down rebar piping and use that in my irons to bring down my flight and spin. Thanks

In general, it does nothing, but it depend on the shaft design
- A shaft like Rifle for irons go stronger when going longer (more butt lenght makes them stronger), while other shaft designs with a "relative" weak butt go slightly weaker.

Length is #1, and will always overrule importance of flex, so dont get hung up in BUTT flex alone, its way down on the list.

Spin rate with the driver is influenced from impact spot on the face. If we cant pure it, but impact below center line, spin will raise even if launch will be lower, while if we impact it above center line, launch will raise but spin goes down.

If you by going shorter gets more sweet spot hits, spin will go down, no matter what shaft you play

[size=4]i'm looking to take advantage of the lighter weight shafts, but don't want to give up on performance. i'd say i'm a higher ball flight/spin player. so that is a concern/factor. now i'm [/size][size=4]trying to decide between PXi 6.0 or 6.5. most likely going soft step either option due to purchasing a 3-PW set and using them in my 4-GW. they will be [/size][size=4]going into JPX-825 pros. will most likely play them at 1/2" over mizuno standards (which is what i've always been fit for). currently using DGS300, which i always end up going back to. definitely old faithful for me. haven't found something that can displace it yet. i have tried KBS Tour X and DGX100 (both straight in) and felt both required a bit too much effort to get the consistent results i'm after. [/size]

6 iron ss: 92
mid tempo (optimizer = 5)
mid to slightly early release (optimizer = 6)
5.8 index, play once per week, practice multiple times weekly (a bit of range rat)

anyone have thoughts/comments? or similar experience(s) to share? i don't have any experience with soft stepping.

thanks!

There is no substitute for testing, and there is no "advantage" to lighter shafts, unless the ones you play is to heavy, so im not sure why and where you wants to go with this.

PXI is "soft to flex", compared to regular PX, and since you tend to go back to DGS300, weight might be what you need, so PXI 6.5 soft stepped sounds better than 6.0, but you should try them first especially since PXI is as expensive as they are.

Tom Wishon made fantastic tool for shaft compare, so here is those shafts you are talking about, all strait in. As you can see KBS Tour X is absolutely the strongest, while PXi 6.0 is the softest.
A PXi 6.5 SS1 would be closest to DGS300 strait in, but lighter that DGS.

The highest line is the strongest

Howard, thank you very much for the response! i 110% agree there is no substitute for testing. however, i don't always have access to the exact options i would like to test. which means i end up doing a good amount of expensive trial and error. which is why i research the numbers as much as possible before doing anything. i actually had created that exact chart in excel with the data i've put together from this site. many thanks to all of the hard work and time that you and Tom devote to this site. much appreciated!!

my use of the term "advantage" is really more my curiosity around the performance of the lighter weight shafts. theoretically, if i can find a lighter weight shaft that performs similar to the DGS300 that i keep going back to, than i should gain a little in swing speed, thus distance. this all assumes that i can control the lighter weight shaft and still make consistent, solid contact. basically, i'm very curious about the PXi shaft. tried the original PX and felt it was a bit boardy. the PXi seems much more smooth. i have tried the PXi 6.0 in a few different Mizuno heads (including my 825 Pros) at my local shop, on Trackman indoors. the results seem promising. enough that i'm leaning towards pulling the trigger on a set of shafts in order to give the PXi some real world testing. i just want to ensure that i start with the correct flex or i'll be wasting my time and money. the numbers definitely suggest PXi 6.5 SS1 is where i should start.

how would PXi 6.0 straight in compare to PXi 6.5 SS1? i've seen some info for other types of shafts, but nothing specific to the PXi. curious about what to use in my wedges, assuming the iron experiment goes well.

[Howard_Jones]

Go to the search field in top, and write PXI (this topic), and you will have a lot of info you might have missed.

Ive only measured 1 set to over length and soft stepping in PXI (so another set might be sligtly different), but here is what i found:

mbbrewer is right, it show different options for install, and what FCM values those gives.

X-100 strait in, will be 6.8, and so is KBS Tour S Hard stepped 1x (hs)
X-100 soft stepped once (ss) is 6.5, and so is PX 6.0 strait in, and KBS Tour S+ strait in, and C Taper stiff hard stepped once,
X-100 soft stepped twice (ssx2) is 6.2 , so is PX 6.5 Soft stepped 2x (ssx2), so is KBS C Taper stiff strait in, and so is KBS Tour S+ soft stepped 1x (ss)

You will also find the weight uncut for the shaft as Taper tip

If fitting shows that a certain cpm value will fit a specific player, 1 cpm up or down does not matter, so if target cpm is 6.8 like x-100 strait in, you have this options on THIS chart.

132 Gram - Tour X 7 ssx2 = 6.9 FCM
130 Gram - PX 7.0 SSx2 = 6.7 FCM
130 Gram - KBS Tour X = 6.7 FCM
130 Gram - X-100 = 6.8 FCM
125 Gram - KBS c-Taper S+ = 6.7 FCM
125 Gram - KBS Tour HS = 6.8 FCM
120 Gram - PX 6.0 Hs = 6.9 FCM
108 Gram - X-100 Super Light = 6.8

This chart DOES NOT say that this shafts will feel the same, or perform as the same.
Its only a chart to fit the need for e certain Cpm strength due to club speed and parameters from the players swing who adjust from club speed.

Howard,

does the chart suggest that DGSL have the same Frequency as DGold?


ive been trying an X100 soft stepped once in the DGSl and find it quite playable.

Yes it does, but its not correct. Ive got a larger chart im using my self, but since BUTT cpm is NOT that important, it only brings more questions than answers, so i never posted that chart. DGSL is softer than DG butt side.
Weight is what really matters, the rest is feel and how it works, and then butt CPM is "just a number".

Here is specs on the hole profile from Tom Wishons Shaft profiling software, but like my chart, BUTT/36 is not important at all at standard length since we cut of most of that part anyway, so read the numbers at 31 and down.

[trying2scratch]

Does anyone know if adding 3/4" butt extensions on a kbs c taper (taper tip .355) S flex will soften flex or stiffen it up? Seems like the PX line gets stiffer when you add length but can't find the info on C taper.

My builder says it should weaken the flex but I wanted to check here from peoples experience.

My other option would be to soft step them twice to achieve the desired length, but not sure if this would play softer then the 3/4" extensions. My goal would be to get it down to between an R or R+ (liked the feel of the R in the sim, 6i speed 86, smooth tempo. 6'3 tall) without having to buy a full new set of shafts.

Any help would be great.

Thanks,
N.

So just to make sure I am reading this right? I have a set of Tour Issue S400 shafts and I want them to play like S300. All I need to do is soft-step them one time?

Hello Mr. Jones,

Great great info. A bunch of thanks from China. Some technical questions: how is FCM defined, e.g., CPM is cycle per minute? Also, how is FCM related to CPM, if any?

Thanks a lot,

FCM is Rifles system for flex measuring, also called Frequency Coefficient Matched, where flex labels like 4.0 - 5.5 - 6.0 and so on is used, instead of L.A.R.S.X

A 43.00 long long club at SW D3 who measure 250 CPM is flex 5.0
A 43.00 long long club at SW D3 who measure 255 CPM is flex 5.5
A 43.00 long long club at SW D3 who measure 260 CPM is flex 6.0
A 43.00 long long club at SW D3 who measure 265 CPM is flex 6.5

CPM is Cycles pr minute, or how may time the shaft oscillates back and forward in 1 minute.

When we go longer, within the same FCM flex class, CPM will drop by 4.3 for each iron longer
Ex. #6 iron at standard length 37.50 with a butt CPM of 300 is FCM Flex 5.3
......#5 Iron 38.00 should the be 300 Minus 4.3 = 295.7 = FCM 5.3
......#4 Iron 38.50 should the be 300 Minus 8.6 = 291.3 = FCM 5.3

Go back to page 9, and post 268 and you will find a chart for Rifle, and what CPM value who gives what FCM flex mesured with a 2.5 inch long clamp.

OUTSIDE the chart

Since a lot of you are searching for info about how one shaft performs vs another, id like to fill you inn with some info about the 2 shafts i know the best, and who they are the best match for, and thats DG vs PX

First pay attention to weight.
Weight is a factor, not only for the potential of club speed, but it also influence on your swing tempo and stability in your swing plane
Since standard flight PX and comparable flex DG is far apart in weight, the comparable flexes is not meant for the same player.

DG is heavy, and better if there is a need to slow down and smooth out swing tempo, while PX is for the player in CONTROL of his own swing tempo. If more weight than standard flight PX offers is wanted, Flighted PX one flex class up will get us closer in weight, but then as descending weight

Release timing
The later and more CONSTANT the players release timing is, the better [u]he will be able[/u] play a PX shaft
The PX shaft is more sensitive to variables in release timing vs DG, so if the players release is variable, he will, not get good dispersion with a PX shaft. For this player the shaft profile of DG is more "forgiving". He will see better dispersion with DG.

The key here is CONTROL
The better the player is in control of his swing, and the later he releases the club, on a constant release timing, the better he will be able to play a PX shaft. Any need for smoothing out a players errors or inconstancy, will bias the shaft choice against a DG shaft.

WHY is this different you might ask.
Bend profile and step pattern or lack of step pattern is the answer

If we go by the rules of energy in the nature, we know that we cant make energy, only transfer or convert it if it already exist. In Golf, you the player provides the energy, and the shaft is the transmission of this energy.
A shaft dont ADD energy to the swing or impact, but different shaft profiles eats different amounts of energy in transmission, so the efficiency of 2 shafts might be different, yes even with the same zone flexes.

A stepped shaft like DG, looses energy in transfer of power in each step from butt to tip, but also the lenght of the parallel section, and the speed of the stepping influence on how much power who gets lost here.
DG also has the relative softest part of the shaft in the BUTT, so this is the profile who provides less dynamic loft in the first place.

PX is a non stepped shaft. Is was a stepped shaft half way done, but every step is smoothed out in a taper pattern, as constant as possible, to lower the loss of energy in transmission. PX got it weakest part in the mid section, and that provides more dynamic loft at impact than a soft butt does.

So PX will respond more to different release timing, than DG does, and now you know why.
PX got a lower bend point, and a higher power transfer, when released right, and thats whats make them more sensible to the players release, vs DG

Howard, small question then with the release and tempo of the swing itself....

Now this is with six iron on a range session- typically is my 180-190 yd club and measured my tempo on Ubersense as it is the best I have...Several years ago it was around 95-97 mph

Backswing- .73 sec.
Follow thru- .24 sec.

What does this tell you? Played the following over time with mostly GI irons cause that's what I play
[size=4]Rifle Lite 7.0- Felt good- hit HIGH but hardly any [/size]ballooning
PX-6.5- Felt dull- hit pretty high but NO ballooning
Black Gold X- Great Feel- hit pretty high and close to PX but NO ballooning
X-100- Feel the shaft- best trajectory to me- Balloons BAD into the wind
X7- STILL haven't had them installed- Saving my clams for the chance at Callaway Apex irons with shaft options


Fitted in college but not really since and don't have any rpm, flight etc,etc,etc readings...

Thanks
-David

Your total tempo time, and split dont tell me much, but your preferences tells you might find DG Tour X7 or Monaco TX flex, to be what you look for. Going SS is always and option, but both this shafts is hard to find. (i still got both, but they are discontinued).

According to the shaft chart the PX actually play stiffer FCM so 5.5PX is a 6.0 FCM. Does this also apply to the flighted PX 95s or do they play truer to stated flex and FCM?

[Howard_Jones]

No Project X shafts fits to the FCM system in flex, but some is closer than others, regular PX steel is most off (way stronger), while PXI is close to Rifle and PX 95 to the softer side, so on PX shafts this labels is used just like the L.A.R.S.X system who tell what place that shaft got within its own family of shafts.

True Temper made this chart a few years ago, but it has not been updated with the latest models PXi, PX95, PXvTour, and PXv Tour 39. It ONLY contains Regular PX Steel, PX Flighted, PX Graphite Blue, and PX Graphite Hybrid Blue

Where are the KBS Tour Vs going to fall on the frequency numbers. I assume right in between the Tours and the C Tapers.

[ChipNRun]

Will the FCM chart eventually include NS Pro shafts?
