Par4QC Smart man, he was.
I'm not buying that shit either.
I've tried a ton of drivers/shaft combos through the years. Just going to say no club is going to do that for anyone.
True for you..... because you have tried a ton. You know what kind of works.
I'm the same now. But 20 years ago I had my first fitting as I had a two week business trip with some time to kill, so I went to see Dana Upshaw. I was a 2 HDCP at the time, so I figured I would be pretty close to optimal. Nope, Dana was able to get me 25 more yards on the driver, 20 yds on the 5 iron, down to 10 yards on the wedges. I was using the completely wrong shafts for me (Project X), and switching to a Rifle 5.5 made that much difference.
I expect to see many people get a 20-25 yard improvement for their first fitting. After that, no.
