Okay, I will chime in here. I have just started with CTE. I was a "naysayer" at first when someone mentioned a "system". See I was a good ball pocketer to start with (grew up playing snooker) so I didn't think I needed a system and that "ghost ball" or "contact point" was fine. And for the most part they were. Where I looked at CTE was to try and find a consistent method to help me over come what could be considered as the difficult shots.
Like most, at first CTE seemed like a foreign language but I forced myself to give it an honest try. This meant possibly taking a step back with ball pocketing as well as letting go of my previous way of aiming. It was not easy and it is not a quick fix method for sure. But I took the time and when the "light went off" and I saw what Stan is teaching I have never pocketed balls like that. Now no shot is harder than any other on the table and I don't even have to concern myself where the pocket is. Simply establish the visuals and sweep/pivot and the ball goes in. Of course as it has been said before your stroke is important as well but my mechanics were pretty solid to begin with (always room for improvement though).
Lastly one of the best benefits, which goes unmentioned quite a bit, is that CTE has me locked into a much better, more consistent, pre-shot routine. This in turn has virtually illiminated me "dogging" easy shots.
I understand they nay-sayers as I was one of them but if given an honest effort, because CTE does take some effort, you will find that it is an excellent way to aim. If you are happy with your game the way it is and are comfortable with your method of aim then all the power too you. CTE is simply another way to aim, just like "ghost ball", "object point" etc. I just happen to at this point believe it may be the best way to aim.
Good shootin.....
