Jon custom fit my entire bag, from putter and wedges to driver and even $@!#%. Not only does he show you the the optimal numbers you should be hitting (ball spin rate, smash factor, launch angle, etc) through analytics, he also teaches you everything you need to know about the numbers. Jon will get you the most out of your swing (without changing it!). I think getting custom fitted is a must for anyone’s golf game whether you get it done here or somewhere else, but these guys are the best in the biz.
