RC85i's and center channel

[dave42]

I have whittled down my choices for inwall surround/main speakers to the Polk RC85i's. Are people happy with these? I have heard good and bad things about them. I will be going to Circuit City today to listen to them. While the RC series may not be the absolute best speakers, they do fit my criteria for the best price. (unfortunately, the holes in my walls left by my previous speakers do not allow me to put anything narrower than these such as the LC series).
What would be the best timbre-matched center channel speaker for these RC85i's? Polk recommends the CSi5, which ia a monster. Would I be better served with the CSi3 or the CSi5 along with the RC85i's?
My listening position is about 16 feet from the center speaker position.

At 16 feet I would go with the 5. I would also definitely have a good sub, but that's just my .02

The problem with the CSi5 is that it is so deep, it will stick out over 8 inches in front of my plasma tv, as it is on a tabletop stand.
I also have a Velodyne 15" subwoofer, which will definitely handle all the bass, as I'd assume this center channel will be set to small in my receiver. BTW, my receiver is a Denon AVR-2805 (100 watts per channel).If there is that much greater of a benefit to getting the CSi5 over the CSi3, I would probably do it, but if it's going to be subtle, I would probably just get the CSi3.
The listeneing location is about 16-17 feet from the tv. Thanks again for all your advice.
