What do you mean by offset? If I shoot left eye dominant, center or right eye behind the shot line where does "offset" come in? The offset I'm aware of is pivoting the cue to the shot line so that the cue is now "offset" to the aim line when you got down on the shot. So for players that don't do that, how do you know they are using some kind of offset?
When you shoot a straight in shot, are you visually down the line and matching your delivery to it?
John mora possibly will shoot a zero angle in that manner but he offsets his head, so his chin is on the right side of the cue from his perspective. I assume he is retaining a visual line that is down the line of the target or what appears to be so from his visual perspective.
This is an example of what I mean by offset.
What you are asking in the form of a pivot is what I prefer to call a shaft angle bias or what Stan refers to as an angled cue.
I rarely shoot with a angled cue to my vision line because I offset my whole alignment toward a left, right or middle bias. If I have a ton of left English on the cb, my visual is still a straight cue to the target but the visual picture is what I call a "flag" because the cb appears 90 degrees to the right of my tip back up the shaft. The right edge of the flag being the cue ball right edge, is now the contact point that visual meets the contact point of ob.
So, where is the fkn deflection "sqwirt" now that I'm aiming parallel down the line that everyone keeps yapping about? The deflection is neutralized because my entire delivery alignment is "offset" to allow it, thus it's not parallel that causes the sqwirt effect because English is English.
This is why backhand English is preferred but all that is, is a angled cue and that's fine but how the hell does one judge that "pivot" accurately when cb/ob relationships are out in space and ob is not near a pocket?
You gonna aim for me boy and you better aim good......sqweal like a sow, sqweeeee! Loud'uh......SQWEEEEEEEEE!!!
