Alright yeah, throw a wildcard object in there for VIPER and keep an ear out for anything new. NCSHP & MAMA should be the only other active users out your way for right now.
It also wouldn't hurt to do a band search every few days and check for new sites. Bruce Ridge/Chunky Girl Gap & Murphy should be coming online in the coming months. If Clay is going to be moving over to VIPER, they're going to need better coverage. It looks like Winesprings Bald is the only site that might offer decent coverage...maybe Joanna Bald, but I've never had much luck with Rocky Top in the way.
