If you are having trouble Hitting with the driver I would suspect over acceleration. Try to be more deliberate, positive and heavy (3-F-6). If you deliberately Drive the hands to Aiming Point so that you feel the #3ppt the whole way down I'll bet you'll hit the driver better than ever. Take a wet mop and push it through impact and then try to duplicate that feel (impossible to be quick). Yoda showed me this one and it works. Good luck!
