oops, I forgot to mention ust as well. I have a pair of highrollers from a few years ago that are 2.35, super tacky, silkworm, ust. They have a flexible bead which I assume is Kevlar and feel somewhat in between a 2 ply dh tire and a 1ply xc tire. I'm looking for a matching minion dhf to run up front. So far I haven't found such a tire. The closest thing that I've seen has been 60d rubber.not a retailer link off the top of my head (maybe try go-ride), but BTI shows them: http://www.bti-usa.com/public/category/TR/TRTS/MA/MA204?page=1#MA204 and any LBS can order from them.
