thanks, posters all. FYI I've actually been eyeing a set of avid mechs on ebay for some time now, and the seller didnt mention anything about 5's or 7's so i got confused when i went to avid's site. seemed to me like a new model. whaddauguysthink - bid for the "older model" $135 the pair or wait and get the "newer" 7's? i dont think there's even any difference b/w the 7's and the "older" model.
