This is my first, probably last chime in with all these threads. I use CTE myself and it really helped me a great deal. A very solid system and I back Pro One all the way. I played with Lou numerous times and watched his one pocket games. I can't say that I have seen John play a lot, but I did watch him at The Break a week ago play some one hole, and in my opinion, he doesn't have a fu**'n chance. That's all by watching how he moved the cue ball, not to mention all the shots he missed. Now this has nothing to do with aiming systems mind you, MOVING THE ROCK, IS MOVING THE ROCK, no pockets neccessary.
I have to favor Lou in that matchup.
