[12 piece bucket]

Swinging. Poor shots are a slight push...but even some of the straight shots are a smidge towards the heel. What do you think about the weight starting on the ball of the foot ...then moving towards the toes due to the throw out action? It is more pronounced with short irons (heel)

I would bet you are over doing the karate chop deal and gettting under plane. You are a good player so I doubt you are a roundhouser. So you can come close to the hosel from the inside too. If you got the chop deal going too much you'll start coming from under and the sweetspot will be late rolling off the face of the plane.

Do you have a high finish?
