if its in your budget to afford either or, then i would get the QS8's, and use them as surrounds(side). then get the M22's, and use them as rears.

although i have never heard them, i think you might be able to get away with M3's or M2's as rears. but, i know most prefer direct or front firing speakers as rears when used in a 7.1 set-up.

good luck, and be sure and post us some pics of your system when you get it finished!
