Perhaps the address position with the ball further forward in your stance alters your stroke pattern without you being aware of it.

Perhaps you try to hit "up" on the ball instead of doing the right thing.

Perhaps this creates alignment error in the takeaway. It is very easy to get an OTT-ish takeaway with the driver if you don't insist on doing the right thing. The right thing is three dimensional, btw.

Perhaps all of the above ruins the down part in your three dimensional downstroke down, out and forward.

Perhaps your problem will go away if you just hit a few drives with the club face addressing an imaginary ball that is a few inches further back in your stance.

But then again, perhaps your isue is a different one from this usual suspect
