[Which surround back speakers to get for RF-7 II 7.1 system?]

Thanks for the advice! I'll probably go with a set of RB-81 II's since I found a dealer that is still offering them in the cherry finish.

[Which surround back speakers to get for RF-7 II 7.1 system?]

Hey everyone. I just upgraded to my first Reference line of speakers and am wondering what speakers to get for the rear surrounds to upgrade it from a 5.1 to a 7.1 system. My current set-up is a pair of RF-7 II's, RC-64 II's, and a pair of RS-62 II's. From what I could gather, likely matches would be to get either a pair of RB-61 II, RB-81 II, or a second set of RS-62 II's. Of course I started my set-up right about the time these things are no longer being produced, so I'd like to pick them up before they become hard to find. Any advice on which speakers to get would be greatly appreciated.
