In three cushion billiards it's ALL about controlling the cue ball...as it really is with most if not all 'pool' games.

I am well aware there is an entire lore surrounding this notion that a soft tip gets more action, gets higher spin-to-speed ratio---and that you can find the claim from amongst the best players in the room, the best players in AZ Billiards, pro players, experienced players...


I think this claim should enter the textbooks as a superb example of confirmation bias http://skepdic.com/confirmbias.html

Aside from the subtle contact-time effect on the offset (a smaller effect than the claims), the claims are false.

The force that produces the speed and the force that produces the spin are the same force, and at a given offset any additional force increases the two in the same ratio. A soft tip acts slightly longer, but it's basically less force acting over a longer period, and the added-up result is the same.

There are shots designed to test the maximum spin-to-speed ratio, where you can get an actual top player trying to get maximum action using different tips--basically a slightly-off-angle draw shot where you are trying to hit a rail as far back as possible. I and others have done these empirical experiments, and the results have been consistent and agree with the expectations from the physical description.

Sometimes you need to kill your baby.
