If you've been thinking about it, do it.
If you've been thinking about it, stop what you're doing and schedule a fitting. You're going to have a great experience if you go with the flow, have an open mind, SWING SMOOTH and have fun. I've played for 26 years and been fit for clubs in the past; thought I knew what I needed. TrackMan and analysis of my dynamics punched gaping holes into those beliefs. Going through their process, Mike helped me build a set that was CUSTOM FIT to MY swing to accomplish the shot characteristics I desired with my preferred OEMs...all D3 swing weight!
One piece of advice:
PURE YOUR SHAFTS. The variance in distance between a dead nuts flush marshmallow ball vs a skanky toe shot is ~10 yards with my custom set [JPX 919 Tours]. I saw a 20-40 yard range with my previous set [AP2 710s], depending on the club. It makes a difference.
