I would say it's shaft dependant, I'm a regular flex in driver and woods with a slower swing speed but, I get along great in a F4 (stiff) Recoil 95 in my irons and wedges.Hello from Chattanooga. This is good info, glad to know about Summit for the future.
I have a general fitting question based on the OP's story, and would be happy to hear thoughts from the OP, the fitter or anyone else.
The OP says he was using X100 shafts in his irons before. He says his swing speed is normally in the low 90's but it was as low as the high 60's on the first attempted fitting day.
That's a huge difference! That being the case, do you try to choose iron shafts that match his highest swing speed numbers or do you recommend shafts that CAN accommodate his highest speed while still being somewhat playable on his off days?
Obviously we all have good swing days and bad ones. I play "stiff" iron shafts and I know I fight against anything stronger than that even on my good days. I'd hate to see my results trying to use X flex iron shafts on a day when my swing was off.
