I went to Dave Pelz 3 day scoring school back when he had a School in Austin. While I did nto adpot his 4 wedge approach, I feel I am more confident than ever from 100yds in. I am the best lag putter in my group, and if I 3 putt it is a fluke. It was the best $1200.00 I have ever spent on golf. I recommend it for everyone.
