Been struggling with the driver for months. Multiple lessons, practice, etc. I got fitted for irons last summer (JPX 825) and have loved them but had an RBZ (first gen) driver and didn't think I needed a new one.
After fighting the driver though for months while the rest of my game has slowly improved, I went and got fitted at PGA Superstore (The RBZ was a gift and not fitted for me). In any case, the RBZ had a stiff shaft and my swing speed hovers high 80's to low 90's so they put me into a Regular shaft on the Callaway.
Long story short, I've only played two rounds with it but I haven't hit my old miss. I've been straighter and longer to the point that I have to re-assess certain holes on my home course (played tonight and hit two bunkers that are normally out of play for me and sailed one more drive out of bounds while aiming where I used to aim based on my hard fade/slice with the old driver. The ball just explodes off the club face and has that flight path where it seems to just keep climbing and accelerating through the flight.
I've read a million posts on TST about getting fitted, the importance of the shaft, etc. etc. but I'm still just stunned by the starkness of the difference. I knew my swing wasn't all bad because I had virtually the same miss 95% of the time off the tee but I just couldn't get it to straighten out and my last 27 holes I've not had a single slicey/fade miss to the right. I'm actually missing left because I'm hitting so straight I need to re-adjust my targeting.
I literally cannot wait to get out and hit it again. If I didn't store my clubs at my course I'd probably have it in bed with me tonight. I know 99% of this game is mental and just stepping up to the tee feeling like I'm going to crush it is a huge boost.
I love this club. If I wasn't married already I would marry this club.
