Glad to see that Wellsville is mentioned on this forum, and yes, this place is the real deal in riding. I have been to all 6 Hatfield McCoy trailhead systems, and I definitely think that Wellsville tops HFM in difficulty including all black/red trails (which I have done on a sportsquad). Many hill climbs and technical trails here. No rookie belongs at Wellsville.
Also, I agree with the 700xx being a great ride here. I just got mine about a month ago to replace my Raptor 660. A noticable difference in all around performance, especially hill climbs. I would recommend a 700xx in any place like HFM or Wellsville type terrain.
Honda = for the win.
