Generally I prefer to use inside English on the CB also, making the BB in the corner and going 3 rails and out to centre field 
There is another behind the stack break shot that I use, if the BB and CB are both much closer to the stack, with a simple cut into the corner pocket, but hitting the with a regular stroke leaves the CB stuck to the stack, and so, instead I would tend to jack up and play a 1/2 jump shot, where I make the ball in the corner, but make the CB hop up, in a way that it slides across and comes down on top of the stack, opening them from the inside, it is a risky break shot to use, but if you play the CB to come down on the opposite half of the stack, (Playing the break shot from the right hand side of the stack, to bring the CB down on top of the left side of the stack) then you will have a better chance of the CB clearing the stack and having a few shots to choose from
Other than Torsten's break shot, what is the most unorthodox break shot you have seen and/or played in Straight Pool?
