I've read with interest pretty much everything on this forum since February or so when I found it. I quit playing for 5 years, been playing for about a year or so now, and finally got my stroke and game back to previous levels, maybe even a bit higher, based on lots of practice and study and immersing myself in the game again. This forum has been a help and a good diversion at work too...

I haven't commented much on other aiming threads thus far, but this one prompted me to do so.
My take on aiming systems etc. - I never really heard about this sort of thing 5 or 6 years ago when I was playing heavily. I learned basically ghost ball method, and intuitively just aim 95%+ of my shots with no issues, adjusting for speed, english, curve, deflection, etc. pretty easily based on years of playing. Always assumed everyone else did the same thing. Never really heard or read much about rock-solid aiming systems that worked for all shots, either in print, RSB, etc.
So with a truly open mind I treat this as valuable new information I could be adding to my game to improve, just like some "new" kicking systems and other concepts I've added to my game that I didn't have 5 years ago. They are all tools in the belt. In a way it's like a search for the holy grail - if I'm relatively well coordinated, have good eyesight and a straight stroke honed from 15 years of playing at a decent level, then maybe some of those weird shots that come up I won't have to guess where to hit by feel, I can double check myself or just plain use an actual aiming system giving me confidence to make the ball everytime etc. And maybe I go up a notch in play and have an advantage over someone who doesn't know the information.
I do agree with the more scientific of the group (Colin, Dr. Dave, Bob Jewett, etc.) that us math/science guys need to see the geometry explained, diagrammed, etc. for it to truly make sense, and if there is some physical pivoting component to the system that can't be diagrammed on a 2D piece of paper then describe it using as many words as you need, or simply make a video and share. Concepts like backhand and front hand english, pivoting, etc. are mentioned but not always discussed at length, unless you find the right thread or detailed article or video. Sometimes it feels more like it was when I started playing (pre-internet) when everything was a big secret not to be shared. If you want it to stay secretive, then don't mention it. If you are sharing, then tell people how it works without being so mysterious. That part of Dr. Dave's article and other posts I've read I totally get and agree with.
On the flip side, people that have taken lessons and learned aiming systems from Shuffett, Houle, Ron, and others swear by it. And there's the whole "Filipino mystique", what do Efren, Busta, etc. do and why is their game so much different etc. "Spider" Dave seems like a reasonable guy, and from his videos is personable and seems to be a decent player. Even fired back some nice responses to a few PM's I shot him. So if he says it helps, I tend to believe him, maybe even more so than just a random poster. So even though the rational part of my brain says there is no 3 or 6 or x line system for all shots, and infinite adjustments and feel are necessary based on distance, angle, english, etc., there may be something to all of this. I, like Colin I think, would just like to have a reasonable explanation, not even overly technical or a full geometric proof or anything, of what edge to aim to what center, when to go left, when to go right, how and when to aim and pivot and adjust (when approaching the shot, when settling in, on the final stroke), etc. Unless I missed a part of a thread, and if I did someone please point it out, but I can't take anything I've seen and go to a table and test it out. I have to call Hal Houle, and hope that his phone persona is nicer than his perceived online persona, or travel somewhere to take a lesson that I don't have the time or money or inclination to do without more information.
If Dr. Dave got information from somewhere and published it incorrectly or whatever, then I agree that that probably wasn't right. But based on numerous articles and posts I have to believe that Dr. Dave was just trying to get to the truth and didn't mean to necessarily bash anyone in particular. However, I'm not trying to side with anyone. Simply put - inquiring minds want to know. So if there is some great system or systems out there that simplify aiming, or better yet help even an advanced player judge or nail down those shots that just look weird and install doubt, or certain types of cuts etc., then please share. Make me a believer too!!!
Thanks,
Scott
