Since I am now officially saving up for another pair of speakers (see "My Boyfriend Rocks!" post) I have a choice to make.

Here's what I have, tell me what you think.

M22ti mains
VP150 center
Polk Audio LS f/x surrounds (di/bipole surrounds)

I have a few options.

1) Buy a pair of QS4's to use as surrounds and move the Polks to the rear.
2) Buy a pair of ??? to use in the rear, and keep the Polk's as surrounds.

Option 1 or 2? And if option 2, what should I put in the rear? A pair of M2i's? A pair of QS2's? (I saw some on Ebay right now)

fyi - The rears will be about 6-8' behind me, so not all that close.

Am I missing an option?
