This may be presumuous, however, when you keep bringing up "swerve" it leads me to believe you are pivoting slightly. You may want to do a drill that I've used with players that are pivoting and can't "feel" it.
If you need to go TOI to the right start off by pivoting left, THEN move parallel over to your TOI right position. This has worked in a few cases and will quickly give you a new sensation of how the TOI is applied. This is another thing I can see right away and help you with, and in writing it may be difficult to understand, so I'm going to describe it TOI to the left also.
If you need to cue TOI to the left, start off pivoting to the right, then move parallel to the left TOI position. This will show you that the shot line is slightly different than what yours is currently. It's merely exaggerating a "non" pivot TOI....to make the necessary changes sometimes it pays to exaggerate. I did this with correcting a distance/stance issue years ago.
This is JUST a drill and I don't recommend doing the TOI normally like this, however, I'm getting the impression it will help you. When you pivot correctly there's no threat of swerve unless you're hitting a "stun" type shot. Remember, it's the feel of the pocket that you're trying to generate, so you have to accentuate the hit of the cue ball.
One thing I could always tell about Keith McCready is how connected he was to hitting the cue ball. He took great pleasure in connecting to the CB and REALLY feeling the sensation. This is how you develop Touch, that's why I shudder when players start talking too technical regarding the TOI because it moves them further away from finding their maximum "Touch". (and the game will not be their teacher)
CJ,
Thanks so much for taking the time & trying to help. I do appreciate it. I know it is very difficult when we can't see exactly what each other is doing & text can confusing at times.
Swerve is a function of a hitting the ball off center & off of the equator of the ball. It is there whenever that is done. However it takes time to come into play. If hit hard enough the CB will contact the OB before swerve can come into play. If hit soft it can all but cancel out the net effect of the 'squirt' & even cross over the oringinal shot line. It is like a mini, mini masse. A pivot vs a parallel move off center does not effect swerve. A pivot vs parallel shift will effect the angle of the squirt relative to the line to the OB.
That is why many people pivot when using english because if bridged at the right spot for the cue the squirt/deflection will be compensated for & the ball will go to the intended target instead of squirting off line. I generally shot my english with either a parallel shift or a combination of a slight front & back hand 'twist' in opposite directions. I am using a pivot for english more than ever since you've brought TOI online. Normally I would just shift parallel to use english or do the combo front & back 'twist' or just come down on the english side.
All that being the case, I do not understand why you have told me for the second time that you think my 'problem' might be that I am pivoting. The swerve issue only comes up when I don't hit a shot firm enongh to keep any swerve from coming into play on the longer shots. I can create enough 'squirt'/deflection to over cut the ball at times. My awareness of swerve is probably why I tend to hit some shots harder than actually would be needed just to make sure that I get the full effect of the 'squirt'/deflection & do not allow any swerve to come into play.
Before TOI I would shoot with english by using the swerve. It allows one to shoot with english softer than what most people do. I was doing what you do with the 3 part pocket but I was using a touch of swerve(TOS). I 'aimed' for the full hit side of the pocket with outside english. If my swerve is correct, for me, the ball goes into the full hit side as I plan so the cue ball hits the OB as full as possible. If I over did it, it goes center or on the thin hit side. Shooting this way is very much about the spin to speed ratio. I am rather good at it & don't see it as difficult as many make it out to be. I was TOSing balls into the pockets & doing the exact opposite with inside spin.
I see TOI as a simple concept. However my background with utilizing spin & swerve for so long may take more time to wash out of my mind. When I am looking at say a long spot type shot, I know I can make it with either outside or inside spin shooting softer that I can than with TOI. I can do this because I am aware of how swerve works. Mike Sigel has said that 'squirt'/deflection does not exist. You know that it does. He probably knows too, but his focus is not on the 'squirt'/deflection but on the spin to speed ratio & the swerve, as I have been doing for so long. Before TOI, I never gave 'squirt'/deflection a thought. A mis from that would be, in my mind, that I hit it too hard with not enough spin. The spin to speed ratio was not enough, it was too samll, I did not spin it enough for the speed that I hit it. Mr. Sigel & I never thought about 'squirt'/deflection. You on the other hand almost always have it in mind as you are 'throwing' the CB out. Mr. Sigel & I were spinning (& swerving) it out.
When I am shooting with TOI, my main focus is to create the correct 'squirt'/deflection with no swerve coming into play. I know that if not hit hard enough some swerve will come into play on those longer shots. That is probably why I am usually over 'floating' position of where I want the CB to stop & am getting some inside spin off of the rail. That may also be why you say to use an extra rail when possible. It allows a firmer, higher speed shot to keep swerve out of the picture.
If I am 'setting' up not pararllel it may be a visual problem more than it is anything else as I fully understand the difference.
I will certainly give your over correction idea a try. I 'real eyes' from my coaching experience how that works & is sometimes the only way to fix a problem.
Thanks again,
Best Regards,
