I've been using the Dunlop 756 up front for about 9 month's, and it has worked really well in all conditions. After all the snow and rain we've had here, I tried a 773 on the rear. It hooks up real well in the mud and loose soil. But it wears pretty fast, especially over the rocks. I have 3 races and about 7 rides on it, and it needs to be flipped.
