Thinking of p790

I am thinking about getting set of P790 irons, right now I have srixon z545 irons with c taper shafts that I was fitted for. I am 15 handicap. Even with the c taper shafts still hit the ball to high and I am high spin player. I thought with the p790’s would lower the trajectory and also lower my spin. On a windy day feel like I don’t have a chance with how high the ball is going. What do you guys think?

I've owned both of these sets. The p790 go significantly higher than the z545 irons. Maybe look into a shaft change, that head change isn't going to give you the results you're looking for.

P790s are NOT low launch at all. Even at jacked lofts, the 790 3i (19°) goes higher than my z745 5i with a high launch shaft. Lower spin it may be but it is not low launch. That said, the 790 is a rocket launcher. I certainly don't lose distance despite the extra height the 3i gives.

Guess I thought they were lower launching irons. My bad

I thought with less spin that ball wouldn’t launch as high

... Having played both, my experience is the launch was the same playing the same shafts. The difference is the P790's spin less so they are not as effected by the wind as the 545's. To be fair, I did not like the 545's at all and sold mine after a few rounds. But as others have stated, the P790's are not low launching.

Where the CG is placed with the hollow head design of the P790s they are built to launch the ball very high. They strengthen the lofts to bring the launch down a bit, but it is true they spin lower than a traditional muscle back or players cavity iron.

Do you mean initial launch angle (as measured on a launch monitor) or the height of the ball during flight? Those are two distinct, albeit related, things.

Height of the ball during flight

I've not tried the P790 but my expectation would be they *launch* the ball pretty high due to the hot face producing reduced spin and higher launch. But if they're like the other hot-faced irons I've hit, the actual flight of the ball will not necessarily be sky-high. The lower spin tends to produce a medium-high rather flat ball flight rather than one with a very high peak.

Your 790s will launch higher nah shave less spin.

Change your shaft, ball, ball position, attack angle, and if you’re talking about teed up shots, lower the tee height.

The lower CG and that speed foam + tungsten weighting in the 790s make them a high hitter. I put S400 shafts in my 790s and have them play 4* weak and they go pretty up. I’m happy with mine...for now.

The 790's definitely go high. I actually was able to ditch my 4h for the 790 4i because it went just as high but spun much less, so I could get an extra 5-6 yards but not lose decent angle.

If you're a high ball hitter, you won't hit lower shots by just changing to 790. You'll have to probably change your swing and/or set up to get a lower flight, especially since C Taper is already one of the more stout/stable shafts available.

C tapers are “low launch, low spin” shafts but that can be easily counteracted with ball, ball position, angle of attack, etc etc.

Crossfiekd touches on this and I used to be a shaftoid but, in my irons, as long as the setup feels good, I’ll use it.

So I probably have to steep angle of attack that makes the ball go to high? I normally play the ball more off my back foot, just feels more comfortable.

Unless you just have super-extreme high clubhead speed, the main determinants of how high your iron shots go are loft and your swing.

Yeah, some irons hit the ball a little lower or higher and for some people (late release swings) the shaft can tweak the height, as well. But those are fine-tuning type things.

If you hit a 29-degree iron just miles too high (maybe peaking at 120 feet when it ought to be 90 feet or something like that) you've either got to change your swing and/or use less loft for that shot. You can't move the ball 25% higher or lower by changing models of irons or shafts (unless the model of iron or shaft induces you to make a different swing).

So I probably have to steep angle of attack that makes the ball go to high? I normally play the ball more off my back foot, just feels more comfortable.

You also need to consider your dynamic loft. You can "swing down" and play the ball back all you want, but if you do any kind of flipping... that'll toss the ball up higher.

What do your divots generally look like? Super deep... barely any at all?

And, factually speaking... do you actually know your ball is flying too high with too much spin? It's kind of tough for our eyes to see the difference in 10 or 20 feet in a small object that's 100 something plus yards away. Have you been on Trackman or similar lately?

I got fit for c taper shafts and lower my peak height from 150 to 135. The fitter told me I had very high spin. I wouldn’t say I have super big divot

Peak height of which club? What's your typical decent angle with your irons? I'm really surprised a fitter would let you leave hitting your irons that high and not suggest strengthening your lofts a bit.

Got bored for a second and I wanted to see what it would take to produce 135ft of peak height on a 7i (assuming that's what you got fit on).

Using flightscope simulator, you'd need approximately the following scenario:

I assumed you were getting average PGA Tour level ball speed for arguments sake (~120mph on a 7i) as the input, with "high spin" of about 7500 rpm (I tested even up to 9000rpm and it only added about 7ft of total height), and at sea level.

Tour guys can expect average peak height of like 94ft. In order to get 135ft peak height with 7500 spin using 120mph ball speed, you'd need a launch angle of about 24*.

Other guys can chime in if they think differently, but I just don't see you getting that much launch and peak height with out a flip or hitting up on your irons unless you have insane ball speed. If you had typical Tour launch conditions but got 137mph ball speed on a 7i... you could get 130ft of height. That would be roughly 103mph on the 7i, which is certainly possible, but you'd literally be one of the longer dudes on tour.

He did adjusted the lofts down. I can’t remember what my ball speed was. My 7 iron is my 180 club

Is there any irons that have same feel as the p790’s but won’t launch as high?

For 180 total distance and 135ft height... well it depends on your launch but I'm guessing you'd probably around a 93-95mph 7i speed type of swing, but with a little bit of a flip.

Nah, no iron is going to magically take about 40ft off your ball height. Maaaaaybe strongly lofted blades will shave some more height off, but not that much. Lessons to stop that flippy motion through impact, that's probably the key... I'm no coach by any means but possibly you also dip the rear shoulder a bit early which will add a bunch of loft also. I'm guilty of that and that's when I see my ball flight getting high and pushy, I know I'm doing that. When I keep my lead shoulder down longer, my AoA decreased, my strike is better... my path zero's out... literally everything improves. Weight transfer also key.. but I'm getting off topic and I also don't like giving swing advice as I am no pro.

i wouldn't say P790s are super high trajectory irons per se. As others pointed out, it's really a function of your swing (i.e. dynamic loft, AOA). I previously hit everything high, super high spin, playing C-tapers in AP2s. I'm not ignorant, knowing that it's only like that because of swing faults causing a very steep angle of attack. After smoothing out the swing in transition and shallowing the club better, I'm getting a much better flight with everything I have, irons down to woods. Sometimes it really is the carpenter and not the tools. Low to mid double digit HCP players - probably indicates some swing faults and a lack of consistency so I'd say "ball flight" issues that aren't entirely correlated to clubs. A lot of range work has changed ball flight far more dramatically than any new club/ shaft i could have put in my bag.

Coming from a (mostly) Titleist bag, and "hating" on TM for their short product cycles, I tried out the 790s and DAMN... very impressed. Sure ball flight is still high, but got fitted to PX 6.0s to help keep spin numbers down. Who cares about "jacked" lofts, isn't it just about ball flight and dispersion anyways? On demo, misses were misses, pure shots were pure, all as expected. Distance was +1 club, dispersion was about equal to that of my AP2s. While I absolutely prefer the feel/ sound of the forged AP2, the overall performance of the 790 was impressive. Impressive enough that I'm considering making the switch. I'm only waiting to test out the PX LZ 6.0s to compare with the PX 6.0s. Distance is not of concern and I read that the LZ's have a great feel.
