Dbx,
The answer to your question will be found more in the sound that you want through your surrounds than in the wire. I remodeled my home and installed JPS Labs Super Blue 2 for five in wall surround speakers (R&L Rears, R&L Sides and a center surround). The installation also used Seas drivers so as to be voiced the same as my front speakers. I have to say that the quality of the source material that drives the surrounds from both music and video multi-channel is not that impressive.
Unless you have a well defined need for good quality surround sound I would not even think about messing with the wire that is already in your walls. The hassle of trying to run new wire will not produce a payoff that you will hear (IMHO).
Good Luck
