With all talk about checking Loft/Lie on clubs, I was searching around and came across the following. While I am not ready to fix my own clubs, and buy the necessary equipment, I came across this simply tool - $15 - that seems to handle measurements. If I check the clubs, then I can go to someone to fix those out of whack. Has anyone ever tried this (or heard of this)? Is it good, or total junk?
