I went in for a full bag fitting. Grant worked with me to lower my spin rate and increase my smash factor on my irons, with various heads and shafts. Settled on Callaway Rogue X irons, Cleveland CBX wedges, and an Odyssey Stroke Lab putter. There was not much difference in my driver or fairway metal numbers (I think fatigue set in) between my current ones and the newer models. I should have probably did full bag fitting over two separate days. Grant thoroughly explained what each of the Trackman numbers mean, and how we would try to improve them. If you like golf, go see Grant.
