If you are not comfortable shooting off the rail then soft kick off the left side of the 3 moving both cb and the 3 to the bottom rail. Mike will most likely move both balls out.
I am in the camp of moving the 1 towards the 8 with a little inside keeping the cb on the bottom rail closer to the 12. If the 1 does not make it all the way over hopefully it will block the 2 rail on the 8.
