What I meant is to pay as parallel as possible by hitting the top of the cue ball. However, due to the uncomfortable position (in the case of the rail) of the bridge, I am unable to aim properly. I do not believe my aim is consistent.
As for the case when I have to bridge over another ball to play, the line of aim is even more difficult to see since the cue is jack up. I usually don't make these balls even if it is an "easy" straight ball to the pocket. I believe my cue is just not aiming where my eyes are aiming. They are not in sync due to the bridge being to close to the ball in the former case and the jacking up of cue in the latter case.
I think testing of these two types of aiming will proof that most of us are not aiming at where we think we are aiming. Is there anyway to test it? I think my earlier DIY method might be able to test our aiming from the rail but not for that over a ball.
