I'm like Soyel1, I use nothing except the mouse and my memory(or what's left of it). At my current level and tier, missing the ding at all means disaster. The greens to me, seem to change from game to game. Probably just me, but when you play a round at BPB, or any course for that matter, the greens should be the same. I don't mean on different courses, say you play 9 at SA, greens react to the ,8 for tourney speed, you play again and all putts come up short using the same calculations. Sure can make you shake your head. I tested this theory by playing Kia. back 9, 5 times in a row. The putts reacted different on all 5 games. I see no way to predict this and adjust for it, the ones who shoot sub 30 every game, are just damn good, all I have to say.
