Help fixing my iron land angle

[romeyjdogg]

Hey folks,

 

I'll try and keep this short: got refit for new shafts in my OG T200s and have seen some things that give me pause. Well respected fitter put me into X100s and 7i swing speed is 90mph.

 

I have been noticing the ball flight has come down quite a bit with all clubs, and my 5i (longest iron) flight is much flatter than I'd like to see. Was on a trackman today and well struck 5 irons were coming in at 39° land angle.

 

For reference, my well struck 7 irons were coming in at about 45°. Ball flights look the same as when I got fit, but hitting only 7i doesn't give you the full picture.

 

Aside from starting the fitting process over again and spending a lot more money, is there anything I can do? Set is GW - 5i

 

Thanks

My first instinct would be to add some loft.  Barring that buy some new long iron shafts and soft step x2.

Yeah that was a thought I had as well.

 

It seems like GW-7i are acceptable. It's the 6i and 5i that have become the issue.

 

I'll have to look a bit closer at the carry distances, but I think there may be some room to play with weakening lofts a bit. I've noticed that the gap between 7i and 8i is larger than I'd like (15-20 yards), so perhaps weakening 7i, 6i, and 5i would work.

 

For soft stepping, that would involve moving shafts around with different heads, right?

You could try replacing the long iron shafts with AMT White X100's, but you might notice the slight weight drop in the jump to the AMT.

Hmm, I hadn't considered that. I assume the AMT white version would launch a bit higher than the standard Dynamic Gold X100s?

Exactly, you pull all the heads and rebuild by moving the shafts down and cutting to length.  You could also just soft step the long irons.

Cool, thanks for the suggestions. I'll reach back out to my fitter to see what path he'd like to try first.

Hitting off grass or a mat?

This was off good old grass

How do the full specs of the new set up compare with the old?  Grip, total weight, swing weight, length, etc...

From my experience, yes, in the long irons, The 9i/PW shaft is exactly the same as standard X100. Long irons are lighter, and for most people, launch a little higher.

Given that the difference in static loft between your 7 and 5 irons is 6 degrees, it shouldn’t come as a great surprise that your landing angle changes by 6 degrees as well.

 

Fitting high swing speed players into player’s distance oriented clubs with boosted lofts will normally produce this type of result, as the fitter is trying to provide a good degree of forgiveness without resorting to mega-size SGI types. Consider a set of i210/230’s.

Drastically different. My previous set were Project X LZ 5.5 with same T200 heads (standard swing weight, 2° flat), but those were fit years ago and my swing was much worse.

 

Fitter suggested simply changing the shafts to DG X100 because the irons were in great shape.

The previous shafts in these irons produced much steeper land angles and peak heights across the board.

Bending lofts weaker is the fast and easy, and here is what numbers we can expect.
(now im giving you the formulas, so put all clubs into a spread sheet, and use 2 mph as club speed progression)

#7 iron 90 - #8 iron 88 - #9 iron 86 etc...

1.0* loft change at 80 mph, is 208 Rpm (both ways)
If club speed is 10% higher, spin rate will be 10% higher (and vice versa)

90 mph minus 80 mph = 10/80 = 12.5 %
208 rpm x 1.125 = 234 rpm more spin from 1.0* weak, or 468* rpms at 2.0* weak

Descent angle changes with 1.0* when spin changes with 143.5 rpm
1.0* loft and 234 rpm /143.5 = 1.63 steeper descent
2.0* loft and 468 rpm /143.5 = 3.26 steeper descent. (45* becomes 48.26 and that's where you should be)

#4 iron and shorter MUST have 45* or steeper descent to be able to hold greens, and your club speed is right below PGA average level,. where descent is average 50*

Do the math for the full set (clubs speed variables will make a difference for how much spin the loft tweak generates, and by that ho much descent changes), so look over your numbers and see if you can get them all above 45*, and as close to 50* as can be.

You should also take a "gap and dispersion tweak, using Trackman, to make sure gaping becomes good.

That's a lot of good info, thanks. Looks like I'd have to bend these pretty weak to get a 45° land angle on the 5i.
