Under the hood
I was asked by English! to describe my method of shooting. As I said it's not a standard cte system but it uses the same 'pieces'. I use the angle to the pocket to select the visual to use. When I acquire the visuals my right eye is either on or very close to the center cue ball line. I have 20/200 vision in the other eye and it flattens out my view, my natural (only) sight line is directly down the cue stick. I use a half ball pivot to CCB without a 1/2 tip pivot. As Monty Python used to say, "And now for something completely different."
I used to use a pivot triangle to 'compute' the angle I needed. The angle identifies the correct visual needed for the shot. I recently stumbled onto the fact that if I stand directly behind the centers of the CB and OB and find the CP on the OB, the section where it's located will point to the correct visual to use. Post 32 shows how I use the CP information to select between them.
Why do you go through so many steps? When you determine a CP, you can use that directly as an aiming point... I have trouble seeing the CP on thin shots and they're difficult to visualize. Once I have the correct visual the CP gives me, I can throw out the CP and don't have to visualize it on either ball for the shot. Even though it has more 'moving pieces' it's easier for me to use and it's equal or more accurate than my CP aiming for the 45* and larger angle shots.
Here's the steps I went through for a 30* left cut that I tried to break into it's pieces. I stood behind the balls as though it was a straight in shot. Located the CP and saw it was on the OB quarter ball (C) line. Mentally selected a B visual for 30* shot. I can now stop using the contact point. It's only an indicator of the correct visual selection. I don't need to imagine a spot on CB or OB anymore. That's a plus for me on thin shots because I have trouble imagining them using CP aiming.
I think I have my eye directly over the cue ball as I get the CTE line. When I adjust for the ETB line my eye may move off the line slightly but the movement is so small I can't be 100% sure. I hold my cue stick out over the center of the CB and use the left edge of the stick to get a line thru CCB and the right edge of the OB. This fixes my CTE line. I move my attention to the left edge of the CB and move slightly side to side until the edge is at the B point. Sometimes I'll have to twist my head slightly during the process to get an exact lineup. Every time I make a slight adjustment I'll flick my eyes back to the CTE line to make sure it's still set.
Once I have the visual locked, I'll start to bend into the shot. I keep my eyes on the OB for a split second to see if the bend is straight down by noticing the path the OB edge takes. I shift my sight to the extreme right edge of the CB and put my bridge down. I put the stick in the V of the bridge and point at the CB edge with the tip. The stick is at a slight angle as it's brought into position, about 10 - 15*. Hard to get an exact measurement of this angle. I may have to 'fiddle' with the bridge placement at this stage to get the correct angle. The tip is placed so it's completely 'inside' the CB with the right contour of the tip just inside the edge. That's the pre pivot position I have.
Then I pivot to CCB and stroke straight through the center. I may do a small adjustment here too pre stroke, but only to make sure the stroke goes through CCB. The OB won't be in my sight picture on some shots and my attention is strictly on the cue ball. If my V isn't behind CCB after the pivot I'll try again.
I had to work on my stroke and try to get it smooth and straight at different speeds. Still a work in progress. (See my sig for additional details) I had to develop a reliable and repeatable pivot that would bring me back to OB center for a zero angle shot. That was done through trial and error and it took a lot of time. I had to find a bridge length, bridge position, tip placement, angle of tip placement to CB and a smooth movement to CCB.
My accuracy with it isn't as good as my CP shooting. I'd say around 60-65% pivoting. It takes more time to get the visuals and it slows the pace of the game down. Some days I can't get comfortable in my stance, it feels cramped. It's still a work in progress. It reminds me of a '63 Ford I had once. It was hard to start sometimes and if you got going too fast it may start to shimmy and shake. But it could get you down the road a piece.
