Seen Pool101's DVD, and The Otto Zone Trainer, the aiming device that work. I saw work as I tested it with some kids, and saw improvement on the spot. There is a U-Tube of the Otto Zone Trainer here.
I'm certainly not trying to knock anyone's method of aiming or training, but this like so many aiming methods has you aiming at an imaginary spot.
IMHO aiming this way "in and of itself" leaves a large variable even before the CB touches the OB. Let's face it, that spot isn't going to be on the table when you are playing so you have to estimate where it is aside from delivering the CB to it.
Why not aim directly at a real spot? Even if it's close to a 90 degree cut.
Again IMHO there is a much easier way with much less variable. You know the spot on the OB that must be hit, "AND" you are holding a straight edge in your hand when you are shooting.
Think of your cue stick as emitting 3 laser lines. One coming straight off the left edge of the shaft, one coming off the right edge of your shaft, and one coming from the center of your shaft.
Turn on the left laser to cut left, the right laser to cut right, and the center laser to shoot a straight in shot. Look that line right to the aiming point on the OB
straight in>-----------------------------------------
right cut >______________________________
and the opposite side of the shaft for left cut. ( I can't draw that LOL)
If you are cutting a shot to the left, stroke the left edge of your cue stick into the point of aim on the OB. If you are shooting a shot to the right simply stroke the right edge of your cue stick into the point of aim.
Don't use the center of the shaft because it won't compensate for the curvature of the CB. Only use the center for straight in shots.
It doesn't matter what english you put on the CB. Nothing changes, the aiming spot is fixed and not imaginary on the table surface.
Don't go twisting you back hand or front hand just stroke the shot straight and true.
Trust the stroke and put the edge of the stick on that spot on the OB for whatever side you are cutting the shot to. STROKE THROUGH to it.
Do you have the video???

I actually use the trainer to find the line, from the center of the cue ball at contact (ghostball Position) back to center of the cue ball, raise your tip up on the shot line and find the aiming spot on the obj. ball or stick aiming line. That is now your aiming point, either a fraction of the ball or a tip distance off the ball.
Hope this clears it up.

There is no "one way" to aim as is obvious by all the discussions on aiming.
