Few of you guys know me 'cause I post mostly in the 14.1 forum. I'm well versed on the HAMB vs aiming system debate, and I had two reactions after plowing through most of this enormous and detail-oriented thread ("he aims the left edge of the shaft to the center of the contact point, except when he needs another 1.5 degrees of angle, in which case he uses a wrist twist except if the moon is full"):
1. I took some pointers from a guy who went by the name "Pete Charles" in Houston back in the 90's. (Anybody know him?) Anyway, this thread reminded me of him because his approach couldn't be further from the aiming "system" approach. He would recommend setting up a particular shot and just shoot it over and over and over. He had a Zen-like approach to things, and said that you just need to let your brain figure things out. You aren't capable of really aiming the shot correctly because of the curvature of the balls and all the other variables, but your subconscious brain will figure out how to put that ball in the pocket. I realize this is the HAMB method, but it is really a better explanation of what is happening with HAMB. When described this way, I suppose it is an aiming system like any other. You just have to be observant and let your brain figure it out.
2. I'm not trying to belittle anybody here, but I have to say if people spent even 1/10th the energy learning how to control the cue ball path and speed, then they'd be much better players. When's the last time a heated argument broke out over how to control the speed of the cue ball? Who here thinks speed control isn't as important as aiming? What pro players have a trick to help them control the speed of the cue ball, and which ones just HAMB?
It strikes me that there is no substitute for hard work, and the benefit of an aiming system decreases as the quality of player increases. I mean, does anybody REALLY believe that Johnny Archer can't just step up to the table and pocket a ball within 3 seconds just on feel? I realize there are special situations where an aiming system is a good trick (like where to put the cue ball on a spot shot to make a 1/2 ball hit), and it may even be a good framework for less advanced players, but IMO, I think maybe "less is more" in aiming. Let your subconscious figure it out until the shots just look right -- and once it looks right, it will always look right. Aiming is actually the easy part. Delivering the cue with a true stroke at all speeds is the real trick.
End of rant... sorry to butt in.
