There are many things I don't like seeing when I watch golf. One is watching the player pat down the green with his putter on his line near the hole. I know it's legal now, but it still looks wrong. I also can't stand watching modern tour players futzing all around, having these discussions with their caddies, their deliberate preshot routines (which have gotten longer, slower, and more elaborate over the years IMO), and, yes, watching both player and caddie aimpoint their way around every green. I find all of it annoying. But they do it, all of it, because all of these things work, and they are trying to win.
Slow play is a problem, though, no doubt about it. But rather than go after something because we don't like how it looks, I think they should just institute some type of shot clock or chess clock-type rule in professional events. Let the players figure out what they need to do to stay in time. We can't put a shot clock on ordinary golfers in casual rounds, but maybe everyone would speed up a little if they didn't see tour pros having focus group discussions with their caddie on every shot.
I don't think aimpoint is going away. I think we will see the large majority of golfers using it within 10 years. As much as I dislike watching it, I do it myself because it works better for me than reading slope visually.
But it IS just golf and just a game and for God's sake I wish everyone would get a frickin' move on so we can play the round and not spend 5 hours out there.
