I feel like the ball is just under the left shoulder (near my left foot instep), but I probably should double-check it. I've started to carry my dowels with me to the range, so there is no excuse for not validating the ball position, and we know what "feels as if's" can do to us.

If the Ball is in the right place and there is still excessive spin, then the Angle of Attack is too steep (2-C-1 #2B). That is a Plane problem (Zone #3), but the root cause could be a faulty Pivot (Zone #1) or Arm Swing (Zone #2).

It is impossible to tell without seeing your Stroke, but if you will check these things out -- look, look LOOK! -- maybe you can identify the problem yourself.
