drivermaker said:What part of the pocket are you drawing the line from...and are you drawing your line from the same part of the pocket to CB as OB. Remember, all OB's can't be shot at the center of the pocket from a shallow angle with balls close to a rail. You actually have to aim at a pocket facing, otherwise you'll be hitting a rail short. Same thing with a CB. Sounds flawed to me.
Both lines from the pocket start at the same location (either to the OB or the CB), whether that starts at a pocket facing, the center of the pocket, or anywhere in between. Like I was trying to say, I wouldn't really call this a "system". I have noticed that relationship between "contact points" does exist on many shots. I think that trying to use this as a basis for how you aim probably wouldn't be the best idea. I know I don't. In fact, other than noticing the existence of that relationship between the contact points, I never think about it at all. I just posted because it sounds similar to what Colin was showing in his images.
