VJ,
Purchased a Putting Arc a few days ago (the Deluxe model). Spent just a little bit of time with it and noticed a much improved roll of the ball and more 10 to 15 footers going in during the 2 rounds I've played since I got it. I had done a little research on it (along with reading some of the posts here) prior to purchasing it and it made a lot of sense. Although I thought I was making a decent stroke before, the Arc showed that the "precision" wasn't really there in that I wasn't letting the putter head stay exactly perpendicular to the arc on the backswing and I was pushing it "down the targetline" on the thru-swing. I'm impressed with the initial results. As a scratch player who's putting is mediocre at best, I'm anxious to get some more time in with it.
Thanks for what seems to be a great product. And thanks also for the acknowledgement to TGM in the paperwork/instructions that came with it. When I saw that I KNEW there was going to be some good coming out of it.
