I tried the Yokohama AVS's and they were very functional. Also extremely noisy. I am now running on Bridge Stone Potenza RE950's and I'm loving them. The tread pattern doesn't look as cool and you can tell that the Potenza's aren't as sticky, but I'll get more miles out of these for sure. The Yoko's wore VERY quickly. I've heard good things about the contiextremes also.
Aaah, decisions decisions.
Good luck either way,
Elliot
