Since i am moving to the M80's i was wondering , is there any real advantage to using a 7.1 is there enough information to make it worth my while to add my M2's and which is preferable. Obviously front height would be easiest, ie less speaker wire to fuss over.I would really like to hear others thoughts either way.

DOG is GOD spelled backwards.
What others think of me is none of my business.
