When I started playing with Pro1, I setup an object ball 1 ball off the second diamond from the pocket on the long rail and lined up a row of 14 balls across the middle of the table. I used the CueTable tool to estimate the angles of each those shots. Then I went across the line, starting with straight in to what became about a 50 degree shot.
That's how I learned where the transition points were - starting with A or C (depending on direction of the cut), first outside pivot up to about 10 - 12 degrees, inside pivot to about 28 degrees or so (almost 1/2 ball hit). The small overlap area of a few degrees, but otherwise typically B alignment up to about a 1/4 ball hit (49 degrees). Then 1/8, although I think the new revised method is to align to the opposite A or C point for a while first, I haven't played with that.
I also have a doc I put together with typical object ball locations and a wide variety of cueball locations, I used that to train with SEE since the angle transitions are a bit different. It's very useful when training a specific category of shot, since you know what it should be then you can test out your alignment to make sure the ball goes. It's not completely done yet for SEE, but you could use the same thing for Pro1 or any other purpose. If anyone is interested email me at

I'm using SEE now, I find the time I put in with Pro1 has helped me transition very quickly to it, and they are surprisingly similar in execution, when I'm lined up on my SEE ETO line I can still "see" the Pro1 lines as well, basically puts you in the same spot, and it would have to for it to work, right???
