My only negative observation with CTE is this: A player with a good stroke may have lousy visualization skills, as far as determining cut angles. If that player expects CTE to be user-friendly, meaning a system that will allow him to use his good stroke and quickly begin pocketing balls, he or she will be very disappointed because the system does not provide immediate results. I have friends that have bought into this method, only to discover that it takes weeks to months before it starts clicking for them, if it ever does. It's because of the varying changes in the distance between CB and OB. That speaks volumes about the subjective nature of it. If it takes a lot of practice and repitition to get your brain locked on it, it's called rote, which is old-school learning.
Though I'm sure using CTE could provide a quicker learning curve for those that stick with it, a truly objective method for aiming would not require a player to spend hours upon hours trying to find consistent results. Now, if you have a good stroke and I say "aim here", while pointing to a spot on the OB or table or wherever, and you do it and get immediate results, that would be an objective aiming method.
When it comes to aiming, there are two ways to learn: Rote or System. Pick a system and work on it for an hour. If it doesn't provide positive results, pick another one. If that one doesn't provide results, then try another. If you can't seem to find one that shows immediate potential, pick one (the easiest to understand would be good idea) and stick with it until it becomes natural. Eventually you'll get it working because your brain will begin to compensate for all the little things that seemed unworkable when you started it. In the end, the whole process ends up being a branch right out of the old rote tree after all.
Sorry to go off topic, Sacman.
