For anyone who has actually been to demo days.... I will be experiencing my first demo day. Mizuno will be at 2 driving range/courses in my area. I want to test their new fairway wood. Will also test the Ping G15 before that. Is demo day any different than any other fitting? I am also worried about something. Since these will be taking place a one driving range only, the other at a course(assuming at their range), will they be using range balls? And if so, can one get properly fitted using these, since they lack distance and any other true ball qaulities such as tracetory, spin rate, etc? When I was fitted at my pro shop for my irons, they used Pro-V 1s, And lastly, is purchasing at a demo day worth it?
