sixkiller:A word of advice though, DON'T putt from the fringe, sooner or later it will cost you a stroke/whiff!
Just use a higher putting scale, and adjust your feet of power accordingly. Using a higher putting scale may not be the way the game was designed to play a fringe-putt, and some have said it could be a bug, but it will save a whiffed shot and give a player a chance for their birdie without whiffing.
