I have two Conti Explorer Protection's and two Conti Twister Protection's that are available - Both with Conti's Duraskin for added sidewall protection. They are definitely fast and light (Explorer is 515 grams and the Twister is 460 gram, all are non-UST and kevlar bead). I ran the Explorer on the front and the Twister on the back. Both "pairs" (one explorer and one twister) are used, but one pair was only used for a couple of races. PM me if you are interested - I am in Northern NJ
And if you really want to help me de-clutter my garage, I have some other misc single tires that I can throw in, too... (Bontrager Scorpion Air Light, Conti Traction, and a Panaracer Trailblaster)
