Provisional I like to use heavier grips on lighter shafts to balance out the SW a bit. I know “conventional thinking” say you are just fooling the SW scale, but all a sw really is about is feel of balance anyway. The clubs feel different, ask Ping why they use counterweighted shafts in more weight up high doesn’t mean anything .
I have a quick tempo, so weight matters a lot in my world, I like heavy shafts. I have Callaway XHot Pros shafted with Steelfiber 125 shafts and a regular golf pride wrap grip. Earlier in the year I bought a Pinhawk head to try and stuck a Matrix Kujoh 95 in it, knowing that it was going to be lighter and having the notion that I like to make things more complicated than they need to be, I went with the tackimac unified grip on that. I never did get around to scaling it out because I gave it the waggle test and liked it, went out and hit it and hit it well.
My thought was if I get to wedges, I’d want to choke down on them, the unified grip would be ideal for that. I love the grips, it feels so much more natural than a taper, I wish I had found these years ago. Plus, having the lighter shaft isn’t all that bad when the grip brings the total weight of the club back up 15-50g depending on what you are used to. I learned about the heavy grips years ago from BigDaddy (Chuck) on FGI, he has bear paws so he used oversized grips and 7-8 wraps under them. They were a hair too big for me, but the balance of his clubs was always awesome for me. Point of my rambling here is you might want to try a heavier grip to go with the lighter shafts, it works out well for me.
