What tire is better for sand/soft dirt, the new dunlop MX31 or Dunlop D952?

i ride on long island, ny and the track i go to is all sand/soft dirt and when it rains its deep mud. what tire should i go with? the new Dunlop MX31 or Dunlop D952. remember its just sand and soft dirt, nothing underneath but that. help please|||The MX 31 is better in soft sand, but worhtless on anything but soft sand. If all your riding is in loose sand, it is a better tire. But if you ride on a little more than loose sand, the D 952 is better. The D 952 is good for most terrains and it is a long lasting tire. The MX 31 is only good on one terrain and is not a long lasting tire.|||The Dunlop Geomax MX31 is the replacement to their older 773 design. So this is definitely the one you would want in sand %26amp; mud. The D952 is more for a mix of terrain like sand, rocks, hard pack etc...
