Exactly my preference for cutting balls backwards; inside english. As has been discussed more than a few times here, inside affords much easier whitey control. Spinning it in turns the CB loose. Unless you're Efren. And I'm pretty darned sure unless you ARE Efren, then... you're not Efren. Inside, please and thank you.
Is it possible to cut backwards (I assume that means more than 90°) with inside? It could be that he's just using the margin of error from the pocket size.
