Man, I hope I never walk on some of your guys lawns. I use the original AimPoint, because I understand how to read the charts (AME was developed for those who couldn't figure out how to read them). I believe it helps me, in two areas. First, I'm pretty sure that by using it, I play more break than if I just eyeballed it. Pelz demonstrated pretty conclusively years ago that most golfers don't play enough break, and end up messing up their strokes as a result. Second, once I've looked at the chart and picked my target based on what it says, I forget about the read and just concentrate on making a good stroke. My brain is less cluttered, and I believe I putt better as a result. So much of the game is mental, anything that gives you confidence is good.
The way to address slow play is to address slow play. In our last tournament at Baylands, my foursome all got penalized a shot, because we were more than 15 minutes behind the group in front, and played in more than 4:15. That happened because one of the players had the worst reverse pivot swing I've ever seen, and lost a ball on almost every hole. I ID'd him to the tournament director afterwards, just to say I didn't want to be paired with him again. For casual play, groups that play too slow should be kicked off the course. That's the way to get faster play, and still allow people who are still trying to improve to figure out ways to shoot a better score. I go fast between shots, and pull clubs quickly, so that I'm still in position if I want to spend a bit of extra time on the green. I should have the right to do that, as long as I keep up.
As far as the pros go, given how much money they're playing for, I'm not going to criticize what they're doing, as long as they keep up with the group in front. What they do shouldn't influence the rest of us, IMHO.
