Okay; having done some volunteer football coaching at the high school level in a previous life, I suspected that might refer to a pass route where the inside receiver shoots directly out into the flat toward the sideline.

Whichever way you go with the back surround setup, you'll get added enjoyment even from 2-channel source material, since a mode such as DPLIIx can effectively extract the surround ambience from the front channels and direct it to the sides and rear where it belongs.

Enjoy the music, not the equipment.
