I been watching Stan's CTE PRO 1 DVD's and online videos for a while now and have a problem with how to determine which visual to use when the shot is close to being in-between visuals (ie not sure if the angle is 29 or 32 degrees) should I use the "A" or "B" visual. When the shot is fairly close to the pocket this isn't a problem, but when the shot gets further away from the pocket it makes the difference between making the shot and rattling the shot. Has anyone experienced this issue and if so how did you resolve it.
