Hi Ali,
I'm not sure why someone would think that RC MINI CC would be better as surrounds.(?!?) If they are mounted vertically (not like a centre channel) they would have better dispersion in the horizontal plane.
If you plan on mounting them on the wall then RC MINI SAT is more than a fine option since THEY come with a bracket! The CC does not!
The bracket will allow for a nice neat installation and will allow you to aim the speaker accordingly. RC MINI SAT are cheaper too! and actually have better bass than the CC (one woofer in a cabinet is better than two in a somewhat larger volume).
I think I threw in my two cents. . . . Go for the RC MINI SATs
