This was my first experience being fit for a driver. I worked with Rob Sines who could not have been more helpful. Rob took the time to match up shafts with my swing speed. From there we tried different driver heads. Before arriving for my fitting I had an idea of the driver that I was in the market for and left with one I had not even considered based on the Trackman data. I would highly suggest seeing Rob before you spend $$$ on a new driver.
