When I'm above the cueball, seeing the shot in my "mind's eye" my chest is square to the target line and shoulders are level, like I'm talking to someone on the other side of the shot line. This is the best way for anyone to see something centered, with both eyes, at this point there is no dominant eye, they are both working together.When using the aim line as my starting point instead of using the straight shooting alignment CJ suggests, I didn’t start with my foot on the line.
I stood square with the cue pointing at 90° to my hip line.
I then rotated my hip line by moving my left foot forward, moving my head back over the aligned cue.
The right hip slides back slightly, bracing my right leg at the knee, as I fold my left side over to align the rest of the right side with the cue, by hinging at the hip joints.
My back remains flattish, never hunching, if anything curling and arching backward slightly to accommodate a level head.
Like you my initial setup has my right hand next to my hip and my mind now experiences dissonance trying to replicate your setup with my heel/instep under the cue.
I would have to lean my right leg to the left to make room for the cue and hand.
Now getting my head over the cue while leaning left is awkward.
My instinct would be to advance my left foot well ahead so that my right leaning leg rotates into more of a sitting position, allowing me to bend over to the cue line and sight along it turning my head sideways.
Forget the aim line.
Find the spot where your cue, bridge, head and cue arm from vision center to shoulder to vertical forearm to grip with a vertical thumb can deliver a straight stroke using the elbow hinge.
Where are your feet when you are comfortable and balanced with that upper body alignment?
I doubt that your hip is in the way.
My initial right foot position pointed parallel to the cue opposite my hip.
The rotation of my hip plane towards the cue line, as my head moved to the line, rotated my right hip back and away from the cue.
My change to my right foot position kept my heel the same with my toes rotating about 20-30° to the right.
The rotation of my hip line and my shoulder line initiated by the head movement to align the entire right side is restricted somewhat when the right foot is initially pointed straight ahead.
Starting with my hips square, then rotating my right foot slightly allows my head and shoulder line to rotate to a perspective line opposite my right side.
I move my left foot forward at the same time allowing my bridge hand and grip to find the same plane as the perceived head and right shoulder alignment.
Moving the cue tests that where the eyes are looking down the cue and the cue travel are the same, that is the aligned cue.
Setting it on the table and anchoring the bridge hand and arm is ideal position for straight delivery.
The process of slotting the cue then finding the aim line lets you forget your lower body.
The delivery part just needs to be put on the aim line.
Align and aim separately, in that order, to reproduce CJ’s methodology.
I'm not standing at all sideways to the shotline, that's the key to connecting to the shot the absolute best. Then, you must initiate the downward motion with your hips, which causes a chain reaction and you'll drop down to the shooting position with the feeling you are shooting out of the CENTER of your chest. The human body is perfectly designed to make this motion and from the two alignment positions (center/center or center/edge) you can make any shot naturally and many of your shots will feel like you're shooting Straight In, even with an angle.
The left foot is very important because it controls the left side of the body, including the left hand position. I suggest making the left foot perfectly parallel to the shot line, then your left side is also on the line, which puts your left hand automatically on the line.
Shane and SKY do this really well, Shane steps more forward and holds the cue further back than SKY but SKY does is almost identical to how I do, his left foot is parallel to every shot unless there's a ball or the table is in the way.
This takes some time but I'm soooo glad I learned this, it's made a noticeable impact on my game though the years, after learning this I played an entire year, 15 pro tournaments and didn't finish less than 9th with the best players in the world. Anyone can do this, but it isn't easy at first, because it's new and most players don't know how to use their hips to go down to the shot which is vital from my experience.
The Game is the Teacher
