The setup to this shot is pretty easy. Place the two racks frozen to the long rails. Start with the object balls one diamond from the pocket and the cue balls on the center line. Make sure the two object balls and two cue balls are equally spaced. The spacing should be comfortable for you when you bridge the two cues.

I usually end up aiming a little higher than I normally do because my stroke tends to dip the cue tip on this shot. Think of keeping your stroke smooth with a little bit of a wrist flick. I find it works better that way than thinking of trying to overpower the draw.
