I would need a whole lot more info on how they conduct the tests to have confidence in it. If they don't test a bunch of varieties of swing variables across the face then the data isn't valuable for a lot of golfers.
Combination of both, I was fitted into about half of my clubs and took brand consideration/club head shape as well as launch monitor numbers into consideration for everything else (self-fit).
My G425 MAX 3 wood is my favorite, just ahead of my RSI UDI 3 iron. I get 157-167 mph ball speed on this thing and I actually love the stock shaft. I need to find a driver that feels like this club does but just goes further, lol.
This.
I came from C-Taper Lites and my fitter tried getting me up to the normal C-Tapers but it's the most band-aid shaft and you have to swing hard to use them. Further promoting the barbarian like bad mechanics. The biggest thing is the lack of feeling like you can promote good tempo or just...
What's your rough 7 iron swing speed? I tend to be 97-101 mph on course and C-Tapers are one of those shafts that do work for my aggressive swing. They transition and flex in a way that is more "comfortable" than my PX 7.0. However, when I am making better contact and plane is much better these...
If you tend to be flexed then exaggerating the feeling of being bowed but in actual motion might just leave you flat. I tend to be BARELY bowed when I exaggerate it in practice swings, just try it out and get some good video to test the theory.
I usually think I am about 5 strokes better than how I actually played. However, I am stiff on the rules while my friends are not. We don't play for money so I think it probably comes from that to some extent.
Pondering the same, would love to try some MMT 105 TX and LAGP Bryson series shafts. I've been lumbering with the PX 7.0s for a while now and they are decent but I think a change is calling my name.
