I'll check it out, every $ I save, goes back into the golf account. There are a great many views on the putting stroke and far be it from me to suggest which is best, but I do believe that most of the views have one common thread - pun intended - and that is confidence. Look at some of the weird and wild postures/clubs in play and all those golfers think their way is best. Good for them. For me the "screen door" seems natural, despite the problems others have noted that are inherent to that motion. I agree that the golf swing and the putting swing, for me, are the same "type" of motion, an arc, take away...back to square - hopefully... then finish on the other side. Looking forward to reading Utley over the holidays, in the mean time now that I have committed to the screen door, at least in my mind, I feel very comfortable - in my basement - and when I just let it happen, I really like the results.
