i love my 2.3 spider UST's, but i think something a little less might be in order for a grind like this. the 13 mile course has about 3+ miles of road, and another 3 miles or so of dirt road- the remainder being dry+ gravelly singletrack (and rocky). UST tires are probably the first choice, but maybe non-ust and stan's and my mavic 819's will work, too. I want reliability (the only reason my team won last year- no mechs. and no flats), a little lighter, maybe, and better rolling resistance. Any suggestions and good deals would be appreciated.
