what effect does adding weight to the tip of a graphite shaft in the iron head have? Does it affect the ability for the club head to square up? Does it just change the swing weight?
It will change the swing weight, 1 point for every 2 grams you add. It may slightly affect the flex, depending on how much weight is added. Adding weight shouldn’t directly affect the rotation of the face/shaft, although the added weight could affect the golfer’s swing, which could indirectly impact path/face.
