WTB Motoraptor 2.4 for the front. It eats up the trail. The width will help you float through the sand and works good on the rocks and roots. It's the best high speed cornering tire I have found. The Panaracer XC 2.1 doesn't even measure 2.0 and tends to wash out at high speed. Save it for the rear where it does a servicable job, then get a another Motoraptor or Smoke for the rear when you need a new tire.
