Par4QC I've used graphite in irons a lot the past 30 years. It just depends on what the shaft profile is like. I used to have some that were 110g, and they are still the best I've ever used. But, that comparison is made from age 50 to now, even though I've never been that long with irons; 6i was my 'go to' perfect 150. Now, no iron goes that far. 😅
The only set of graphite I have now are the newer Recoil Dart 75. Very nice, and much better than the older Recoil. I am playing steel currently though.
Admittedly, I've only used graphite iron shafts for the looks, mainly. No wrist, elbow, shoulder troubles.
So Rex, let me pick what’s left of you brain since you build sets of irons every day amd a half.
I know it’s a month after I talked about the MMT 105s. I hit it outside alongside a few steel shafts . The MMT looked like a winner in the air. When I went back to Trackman though, it spun 1000 rpm’s more than the others and I lost 7 yards of carry.
I like the feel of a slightly heavier shaft amd I don’t lose any ball speed. Trackman showed me that. The project x 5.5 at 115 grams was good too. The MMT 105 also comes in TX at 113 grams.
My question for you is how would a double softstep on the TX be? The shafts do play stiff which is why I’m thinking double. I just like the weight.
And there is a lot of talk about the shafts being “tip heavy”, which makes them swingweight high. Maybe that’s why they felt flimsy to me… too much head feel. The swingweight issue I could solve with going 1/4” shorter and the 3 grips under the grip.
