After studying the video many times, I think I have finally identified the cause of my towering banana slices, which is, as can be seen from the moment of impact frame below, hitting off of the toe.
I also hit all my irons consistently to the right. I adjusted for this yesterday at the range by lining the ball up with the heel of the club, for drivers and irons, and was amazed by the results.
My question is, should I leave well enough alone and continue to line the ball up on the heel of the club? Or should I try to correct my swing. I feel myself bringing the club just noticeably inside during the swing, but I have no idea how to change that, or if I should.
