For future reference, and for the record, here are some of the
important unanswered questions that still remain:
quoted from dr_dave:
"THICK HIT"
dr_dave, concerning a "thin" hit:
1. Align the cue 1 tip to the right of the CB center through the right edge of the OB.
Spidey:
Not true.
OK, then what is done instead?
dr_dave:
3. Pivot the cue (without shifting the bridge at all, so the cue rotates about the fixed bridge-pivot point), until the cue is pointed directly through the center of the CB.
Spidey:
Almost never. You almost never turn from the bridge - depends on the length of shot. The edge used can affect your pivot.
Please be more clear on "almost" (when?) and "depends on the length of the shot" (how?) and "edge used" (I thought the OB only had 2 well-defined edges).
dr_dave:
4. Stroke perfectly straight along this line.
Spidey:
True. You can also "crash" the vertical planes together with the turned cue.
Please define "crash the vertical planes together"
"THIN HIT"
dr_dave:
1. Align the cue 1 tip to the left of the CB center through the right edge of the OB.
Spidey:
Not true.
OK, then what is done instead?
dr_dave:
2. Place the bridge hand down with the cue exactly along this line, using a 10-12 inch bridge length.
Spidey:
Mostly; however, it depends on the shot length
OK, how much should the bridge length change, and when?
dr_dave:
3. Pivot the cue (without shifting the bridge at all, so the cue rotates about the fixed bridge-pivot point), until the cue is pointed directly through the center of the CB.
Spidey:
Almost never.
Then how much do you pivot for different shots (i.e., how much before and after "center" do you stop), and when do you pivot exactly to the center?
"GENERAL"
dr_dave:
If you follow the procedures above exactly, you will make shots within certain limited ranges of angles.
Spidey:
True - because you're pivoting "randomly."
I'm not sure what you mean. The procedure above has a clearly defined pivot. How do you define your pivot differently, and how do you change it just the right amount for a wide range of shots?
dr_dave:
Now, you can make the procedures work if you compensate a little as the cut angle changes. For example, you can adjust your bridge length (this has a huge effect on the results of the pivot step per Diagram 4 in my December ‘08 BD article)
Spidey:
Never wanna mess with that unless it's tight quarters
So you agree different bridge lengths will have different effects on any pivot? Sometimes, aren't we required to use different bridge lengths (e.g., because of surrounding balls or rails), and don't some people prefer a shorter bridge length with a softer shot?
What is different about your procedure when you are in "tight quarters"?
dr_dave:
modify the starting tip position a little, pivot slightly less or slightly more relative to the CB center,
Spidey:
Nah - it should always be the same.
OK, if it is not 1 tip, then where should it be?
dr_dave:
and/or you can shift your bridge hand slightly during the pivot (e.g., by pivoting with your hips or body) to create a different effective pivot point farther back or closer up from the bridge.
Spidey:
This happens inside of your bridge--- your bridge hand shouldn't shift - but you SHOULD do the above mentioned technique. That's where people get lost - they always rotate the cue from the bridge (which almost never happens).
I think this is the key to the system ... deforming your bridge just the right amount during the pivot to achieve the exact line of aim required. Does this come only with practice, or are there some guidelines that can help?
