A monster shot that I first seen when Babyface shot it in Johnston City, is Bank the 11 ball into about 1 1/4 diamond up from the corner. With a hard draw stroke and left hand english, pull the cue ball into about 1 1/2 diamonds up from the opposite corner pocket. The cue ball will contact the long rail and then spring down to the opposite long rail and up table. The 11 ball will crash into the side of the rack and anything could happen, all of it good.
Something like this Fred? Not a bad idea. You'll definitely move a lot of balls towards your pocket.
Just don't forget that something can always go wrong when you hit balls with speed into the stack. Things like this:
Always a possibility.
