I addicted to looking at golf equipment. Today I demo'd a
Callaway X460 with a regular
Callaway shaft. Don't ever think a new driver means it's better. I have a
Mizuno MP-001 400cc w/ reg shaft and I can't believe the difference. The
Callaway's "reg" shaft was so soft I couldn't get the head to go where it should. I had no luck with it at all. I might try the stiff shaft version.
All I can say is you must test out anything new before you fall for the hype. It's mostly BS.
