You need to learn both types because when Banking with TOI you are producing inside spin, and pivoting you produce "outside" spin on the cue ball. Both of these are necessary for cue ball control. Anyone that banks with just center or outside is missing out on a whole other deminsion of the game.....the 'Touch of Inside" world, and that's the one Efren has used to amaze one pocket players. Virtually every shot that Efren produces that people go "WOW" is produced with inside on the cue ball......we use it to "Stun" the cue ball severely, as well as bending and edging the ball behind the stack on one pocket runs.
The TOI Banking also produces the pocket acceptance spin where the object ball bends in towards the center of the pocket, giving the player a larger "pocket zone".
The TOI AND the Pivot System are initiated with the back hand, which steers the action and is also coordinated with a slight "roll" in the weight of the feet. I show this in detail in the TIP Banking Secrets which can be seen for $4.95 at
