Take a closer look at that 3 ball straight-back. I don't think it can pass the 5 ball wide enough to bank the 3 into the hole. It might be possible to bank it into the 6 ball, which wouldn't be bad.
My first choice was the 8 ball 2-railer, PROVIDING that the CB can be drawn back into the 2-5. The 8 has to hit no closer than 1/2 diamond from the upper corner pocket to avoid the point. The 8 ball won't go, but it should end up near the hole. The CB leave is excellent, leaving nothing but a dangerous kick for the opponent.
The 11 ball 2-railer is a nice shot, but I don't like leaving the CB out in the open. Too many possibilities for a return escape.
