Oh I've read the various threads/posts on both tires, Bill Boards and Avon's. Jamo, in particular, seem's to like the idea that the Avon's are a bit more robust in strength (for trips and such) than the Bill Boards. Still, in either case both are "race" tires at the end of the day.
I was wondering what Grubby disliked about the BB's in order to add to my understanding of what folks in general don't seem to like about them. "Wandering", for instance, seems to be a common complaint, personally I never expierenced that to speak off. Or, it was never a big issue for me. To sticky is another one, but if they weren't sticky that wouldn't have superior traction either! Sticky is a plus from my book. Thin wall, fragile, eh, I guess you could say that (extreme light weight is pretty cool). But there is plenty of folks who put a bunch of miles on them, including me, without any undue issues. All though, I avoid dirt roads like the plague.
From what I'm seeing on THIS thread, Avon's are good for about 7,000 miles or so? Unacceptably low mileage for the cost per tire.
