Has anyone been lucky enough to get their hands on a 917 yet? Or perhaps read about performance advantages over the 915's?
I've only recently put a 915 fairway (15 degree) in the bag after an official Titleist fitting session at my club, and it's a serious upgrade over the 910.
The 915 driver has only been in my bag for 1 year - best driver I've ever had - and I'll be very reluctant to feel the need to switch again so soon.
Happy golfing.
