Every time you watch the Golf Channel or pick up a golf magazine at some point the words swing plane will come up. To understand what this is think of the butt of your club pointing at the ball line on the backswing and follow through. This would be the thought with any full swing shot. Personally I don’t think you can keep the club in a single plane, I like to see the back swing plane a little more vertical and when you shift your weight toward the target the club will drop into plane. So as you can see the club drops slightly with shift the way Couples, Trevino, Furyk and on and on attack the ball. Set the club into plane with your wrists and let it shallow into the perfect angle by impact, the money move! Good luck with this game and shallow out coming to impact!!
