These are the Armadillos I currently use: http://www.specialized.com/bc/SBCEqP...jsp?spid=35646
They make them for mountain bikes too. See the whole range here: http://www.specialized.com/bc/ibeCSrdSrchResults.jsp
I can't say whether these are better/comparable to John's Continentals, but it's probably worthwhile to compare.
John - BTW - do you follow road cycling closely?
John, I don't really follow cycling too closely. In the past I've followed Lance and the Tour, and I study the technological developments a bit, but that's about it. I'm mostly just a hack fitness/recreational rider, but I do push myself reasonably hard when I'm out there. I am fortunate in that the metropolitan region where I live has hundreds of miles of paved bike trails as well as hundreds of miles of maintained gravel trails, much of it rails-to-trails.
