I had my fitting with Jon last week. After a brief warm up, the fitting began with hitting my current 3 wood. I had a typical sample of 5 swings with all the data points that are provided by the Trackman.
Then came the process of trying to find the right shaft. I tested 5 or 6 shafts with the same head. Hitting each one around 5 times. When we were satisfied with that selection, we moved to heads.
I had no prejudices that I shared with Jon in regards to heads or shaft weight. I hit 3 different heads in varying degrees of configuration.
The final configuration optimized ball speed, spin rate, and angle of descent. All in all, the process took about an hour and a half.
