I have the Avon Venoms. In fact, I just had them installed last Saturday (coming of the stock Bridgestones).
I've only got about 100 miles on them so far but I see a HUGE difference in the handling. Where the Bridgestones would track into every friggin little rut, cut, and lane mis-match, the Avons go across them like butta'!!
