Have C Taper lite Stiff in my RSI Tp Irons and I’m losing distance! Seems to spin to much even though Trackman said different!! Don’t trust the thing!!! What would be a better shaft for me with 103 driver swing speed. 86 6 iron speed. I am PGA pro, 55 years old; don’t play much anymore, but I want a shaft that will give me some distance but maintain accuracy. Mid flight preferred. Hit my Cobra MB’s further than RSI’s. MB’s have Dynalite Gold XP Stiff in them! Appreciate any suggestions since Trackman indoors is a crapshoot!!!
