I am with logicalone and Pa-Playa. Once I have a good driver, it is better to leave it alone. I am keeping two now. 45.75” M4 for longer courses and a heavier 44” F7 for tight courses. The fact that I have hit them so well for extended periods tells me that they work. Bad days are on me.
Irons are another story, I spend way too much time and energy fretting about why they aren’t quite right. I think that is all because of swing fiddling (that I don’t do with my driver). Just last night I resolved to get off the merry go round, stop all the messing around, and get my life back.
Steve, could it have to do with your simulator session? Trying to swing harder?
