Just a quick thought, because I had trouble with driver dropkicks. (you didn't mention anything about iron chunks.) Make sure you are not losing your wedge and bend in your right wrist. It throws the arc off. My problems were because the ball was up on a tee, and I had ancient artifacts left over of lowering the hitting shoulder and tilting the spine to do it. These were junk left over from the "hitting up" with the driver delusion. Good luck.
