I want to say that learning CTE will really expose all the flaws in your stroke more than anything else.
Once you are finding the true aiming line any body english will throw the ball out of the pocket. I personally believe that many people have learned to play almost all of their shots with a little helping english because they are not seeing the right shot line. And I think that this severely cuts off the positions that they can comfortably get the cue ball to.
If you have been used to gearing the shot with a little outside spin all your life because you have found that to be the most consistent way to make the ball based on how you see the shot line then using inside spin becomes really really tough.
But once you learn CTE then you find yourself on shot lines that are actually not comfortable at first. This is where using that same old gearing throw will take you out of the pocket where previous it took the object ball into the pocket.
So after I learned CTE I went back and worked on my stroke, actual physical training with a top instructor here and it has paid off big time. Now I sometimes slip into the old habits and then I miss shots. But not because I was aimed wrong.
I have done an amateur video on this concept -
