I hit my current driver and Alex W. identified 3 key data points I needed to address to gain distance and accuracy. Through different combinations of shafts and driver heads I could see the data points improving significantly, through that process there was no doubt which driver gave me the best results. You have to commit to their concept that they are "brand agnostic" and trust the data. I purchased a drive brand I never would have expect - but I am absolutely confident it was the right choice - GREAT EXPERIENCE!!!
