What surround speakers to pair with Aerial LR5s


I have Aerial LR5s with a CC5 center and Paradigm subs.
I have a pair of cheap Surounds (Energy) that came from my old system. I am looking to upgrade the Surounds to a good set of Dipoles but am reluctant to spend $3400 for a matching pair of Aerial SR3s. The question? Should I spend the bucks for the matching SR3s or is there a good set of alternate surrounds that would match what I have? Triad Bronze dipoles have been suggested. What do you think.

Thanks for the help

On thing to consider, which I have done and actually continue to do, is to put the SR-3 on the back wall facing forward. I am actually running 2 pair, one on sides, and one as rears, on the back wall, facing forward. The are about 3-4 feet apart, off the center of the wall in back. I ran them this way in 5.1 without problems, and just recently added a second pair for sides. GIVE THEM POWER, RUN THEM FULL RANGE.
