Mike, just for the record, you can't get any more spin by swiping across the ball than with a straight stroke. Whatever stroke you employ, the maximum spin/speed ratio is limited by the coefficient of friction between the tip and the ball. This is a function of the materials involved, and not of the type of stroke.
It's true that if you swipe across the cueball and, say, make contact at centerball, you're going to put a little bit of spin on the cueball. This is, sure enough, spin you wouldn't have produced with a centerball hit and a straight stroke. But that doesn't mean that if you make contact near the miscue limit (~ 1/2 ball radius) while swiping, you're going to get some extra spin. You'll either miscue or end up with the same amount of spin as you would have obtained by cueing right at the miscue limit with a straight stroke.
You can test this by plopping the cueball down on the headspot and driving it straight to the foot rail while attempting to impart maximum sidespin using both techniques. I think you'll find that the only thing the swiping does is to increase the difficulty of accurate tip placement.
