I've got the 130/70 on my TBS wheel and 18" TBA hoop, but I haven't had the time (or the weather, or the health) to mount her up. I've always had Avons since the original tires and I've tried the 100/90 and currently the 120/90. Don't know that I have enough experience to tell the difference but the 120 didn't feel any "heavier" than the 100.
