Have run 2.3 /2.1 /2.0 versions of the Barracuda, Python and Bulldog MRC med and MRC high on Northern California coastal dirt, hard packed (like concrete sometimes), with small loose stones. Pythons are the fastest on the street and hard packed, but don't stop or climb on loose stones (tread too tight)that well. Great for Downieville, Bulldog on the rear climbs ok, stops well, but still not that good climbing on loose stones, and rolls a whole lot slower. The Barracuda in all sizes seems to be the best--almost as fast as the Python on hard-packed, but far better on anything loose.
They all corner better than any Maxxis or Michelin I have run
Got to know what you are buying with Hutchinson. different models like the Tubeless light and the MRC high have different casings. the light 127tpi the MRC has a 66tpi. If you are flying down hills, with rocks get the MRC casings. they roll slightly slower per tire, but they are really tough. The MRC Medium rubber is about 42d. the High dual compound 50/60 if I remember. The XC light tires are in the 70d range. The Lo is somewhere in the 30d range.
I have also tried them on Mavic 823 and 819 except for the 2.3 Python, that comes out a bit square on the 823 rim but works fine. the tires don't seem to care what rim they are on
So depending on your riding pick the lighter rim. The 823 are silly strong. I have run nearly an entire DH course on a flat tire with no rim damage. (blew the sidewall on a Michelin DH24)
