I have played the 9.5 Tour Version with a regular flex shaft for the past 3 rounds and can reliably say that I have not ever hit any driver further.. It did take a while to get used to the impact sound which is quite dull and "thuddy" sounding to me. Kind of reminds me of the Yonex drivers of old. But when looking at the results, I can certainly get used to the sound very very quickly..
