monumaker Welcome to the forum, never have tried the avons, let me say the diablo corsa III have put me on my ass in cool wet conditions.
joe is not only a fair weather rider, I want a tyre that sticks to the road no matter which conditions i am in, if it costs more $$, I do not care,
I want to stay up on 2 wheels in all weather, I ride through wet clay on the roads surface at times,
not the place you want to find out the traction was not what you thought it was, I want the best traction in in all conditions.(a tall order).
the problem that i had seen with the 208 RR's, they were slick when wet. but i wore the rear out in 2000 miles. great warm dry weather tyre.
