What an improvement over the ft-i
3 June 2011
Summary: Tried out the Diablo Octane driver at a manufacturer's demo tent. Hit it as far against a 20 mile an hour wind as my best shots with the Callaway ft-i minus the wind. Bought the club 3 months ago and my drives are longer by 15-20 yards and much straighter.
