Then the same will be true for any cue. With the same tip offset you might get more or less power (RPMs) with different cues, but unchanged spin-to-speed ratio (angle change off a rail).

“Amount of spin” in pool means spin-to-speed ratio, and is determined only by distance from center the CB is struck - speed/force of stroke changes the CB speed, but not its spin-to-speed ratio.

I think Shane’s speed/power is enhanced by him standing up during the shot stroke and swinging his whole arm (rather than just the forearm), giving him greater “leveraged” speed/power at the grip hand.
