HI,
Yesterday I tested alumine tape that I bought from a hardware store. I cut a piece that covered my club face. After hitting the ball the mark of an impact was very clear. I used the same tape for about ten shots.

Alumine tape is strong - it does not tear easily. This helps to remove it from the club. The tape cost 2 € a roll. I think that I might get about 100 impact tapes from it.

This worked for me. Idea has from Timo Ristikivi - our junior coach.

Looks like I am hitting the ball with a little too much on the toe of the club and a little too down.

Hannu,
