There is alot to hit a Driver. More than just the setting on the club loft and lie angle. It all starts from the set up. First thing is are you on line with your target. Is the Club started out lined up properly. Is your grip right. Is your back swing the right tempo with the right amount of turn and control. are you swinging down on plane. Are you lagging the club properly. is your swing inside to out, outside to in. are your hands stying open at impact. Alot more affects the ball flight than the setting. My guess is you have an out side to in swing and when the ball flys on a striaht line is left of your target line. Im guessing you have as strong ouside to in swing while leaving your hands open at impact. This can come from standing to close to the ball, Pushing with your trailing arm (Casting) and just bad timing on when to squar your hands at impact. Alot to consider. I would say have your Local Pro take a look. Im sure RC will have some Good advice on this.

Just be comfortable at setup and lay the driver down.  Then let the 910 technology do all the work!
