With all the shaft choices out there I think I’d be fine finding something under $50
Grafalloy pro launch red could be found at a good price, if you can find any axe 6 (non tour version), UST V2.
I think what needs to be thought through here is this a equipment issue? Wishon says that a shaft change can only account for 400 rpm of spin. So the rest is the club head or the swing itself.
I’ll be the first to admit I love switching things around and trying new things on the course. If my mind and body picks up on something it doesn’t like my swing goes to shit quick. So yes wishon is talking only 400 rpm but the human factor also is not being weighed in on at all.
Is the answer for the op to get a new fitted driver? Probably yes, but hell its his money and if he wants to spend it investigating other options that’s his right. 😀
