I play about 100 rounds / year (either 9 or 18 holes). Currently 17.3 index. I'm very interested because I currently play a Ping Karsten TR Anser 5 which I BELIEVE has a similar idea with the white milled lines into the gold / bronze colored face. I got it as soon as it came out because I remember the marketing saying that they figured out a way to make mis-hits go similar distances to hitting the sweet spot by using this special face milling technique. Wish me luck!
