I agree that you have to align your body to a shot in a consistent manner for each shot. There are aiming methods out there that incorporate this into the system. But if you select the wrong vizual, and align your body to an incorrect line of aim you are still going to miss...but you will miss consistently!The topic of "dominant eyes" hasn't come up much in my conversations through the years, I just always agreed with the legendary golfer Bobby Jones who said "I'm not sure about the dominance of the "master eye" in golf, I just know I play better with two than I do with one."
I've tried to play with one eye...either eye and it's impossible for me so my alignment is directly behind the "line of the shot," - I look at both cue ball and object ball as I would anything else I'd naturally look at.
I align Center CB/Center OB with my body most of the time and with thinner cuts I align Center/Edge and also favor CTE when close to the object ball. This just gives my mind a consistent relationship between CB and OB...then I create the cut angle by aiming at the cue ball....less cue ball (connected to the OB) produces more cut.....very simple, very easy. I create these angles using my TIP, and it's very reliable.
When I target the cue ball, I move this target spot with my footwork. I don't like to move my cue without initiating the movement with my feet. Like all of the great games, tennis, golf, baseball, basketball, - Pool also requires footwork to aim properly.....the upper body angles can only stay consistent if the are connected to the foundation properly and the foundation of the pool stroke is the feet and the bridge hand.
"Aiming" and pocketing balls at a high level requires more than good eyesight or your cue positioned a certain way, it's about consistency in all aspect of you body alignment and stoke. Pool is NOT natural to the human body, we were not placed on this planet to play pool so the body positioning must be learned properly. Like they say in golf "if it feels right, it's probably wrong"......'The Game is the Teacher'
Since I've switched back to parallel aiming its completely switched my psr and how I step into a shot, how I address the CB and how I set my standing body position when figuring out the path of the CB to OB. Once I've got my contact to contact point line locked in, my right foot stands on that line with my toes pointing down the line and my left foot moves out 90 degrees from the contact to contact point line with toes pointing outwards. then I just lean down into the CB. Those simple steps in aligning your body to the shot line, for me anyways, gets me aiming center ball along the correct aim line.
Very easy to do, but as I've said before if your eyes can't select the correct contact points to pocket the OB, how can you possibly align yourself correctly?
