Been working for a while on swinging less under-plane and more to the left. It's been a struggle. Hit some good drivers at the range today, but the misses were in the heel and pulled. I've been described as a classic overdoer, so I wanted to check in to make sure I wasn't overdoing a good thing. Only thoughts right now are to take it up, left shoulder over right knee, drive the right shoulder at the ball. Any thoughts would be appreciated.
