i'd go with the yokohama's because they're pretty good and pretty cheap. of course, if i had the cash, i'd get the Bridgestone Potenza S-03's.
EDIT: i currently have a set of yokohama avs intermediates. i like them a lot. in september, i needed new tires so i went on tirerack to get a set and they were about to discontinue them and i got a deal: $67 a piece. it was pretty sweet. they wear kind of fast though, my last set i got about 18,000-20,000 miles on them.
