You apparently make that work pretty well. Those who can visualize a parallel line might do it a little more easily (without micro-adjustments). pj chgo

Yes, I believe that's the one Mensabum is referring to - again clearly showing that it doesn't work as described. If you hit the object ball with the CB's contact point indicated by the dashed line from CB to pocket, the object ball's path will be parallel to that line (i.e., will hit the end...

Here's a diagram showing why the lines through the CB and OB must be parallel in order for their contact points to connect. The black lines are the object ball and its path to the pocket. The red lines on the left are the cue ball and its path to the pocket. The red lines on the right show...

That’s only half of it. The other half of what he's saying is to find the spot on the cue ball that’s closest to the pocket and connect the two points - but they’re impossible to connect because the lines aren't parallel. pj chgo

Except those points can’t connect - it’s physically impossible. It’s only possible when the two lines are parallel - that’s why the correct version is called “parallel lines aiming”. pj chgo

Yes, because a smaller tip would have less "end mass" in the first several inches near the tip, so produces less deflection. They reduce (not eliminate) deflection by reducing "end mass" by boring a hole in the shaft for the first several inches at the tip - they even have a patent on the hole...

The excellent book Pleasures of Small Motions emphasizes this point. Focus on the process (stance/shot), not on the outcome (game/match). pj chgo

Why not? pj chgo

About a half ball hit, so pretty much maximum throw. Do you tend to hit it fat? pj chgo

That's where Tip Piks show their value: quick and effective roughing without removing leather or changing shape. pj chgo

Is that R2D2 driving it?

Thanks for the info. FYI, with those dimensions*, the CF walls occupy about 31% of the total 12mm shaft's cross section area. pj chgo *(Assuming "outer radius 6mm" means overall diameter = 12mm.)

Do you keep it shaped (not too flat)? pj chgo

It's also the point on your shaft/cue that's directly over the centerball aim line when angled (pivoted around that point) correctly for the shot's squirt. The distance from the tip to the pivot point is the cue's pivot length. The amount of squirt produced (ignoring swerve) is equal to the...

If that measures stiffness, I don't think it matters much for a squirt comparison - squirt is generated primarily by end mass, not stiffness. pj chgo

Or at least its triangles are... pj chgo

FYI, every triangle’s interior angles total 180 degrees. pj chgo

Easy to see how it seems true (lots of players believe it), but larger doesn’t actually help. Flatter can be a tiny bit more forgiving... pj chgo

The bases of balls (where they touch the table) are clearly visible indicators of center ball that can be helpful visual aids for aiming. I don't know any particular methods, but I think it's come up here a time or two. pj chgo

[broken record alert] For a given tip offset, the amount of squirt produced by a shaft is a fixed angle from the cue's direction - changing the cue's direction doesn't change that fixed angle (the "amount of deflection"), only the direction it's pointed. Sorry to be so insistent, but I think...
