the old style mtr's suck around here.  a buddy of mine is diehard bfg but hated the km2 tread design so he got the mtr kevlars.  they just plain work. muddy trails with off camber hill climbs and some rock.  creek beds and steep hills.   he DD on them and wear so far looks good.  they are bigger than my 35 km2.  i dont like the look of them but they cant be denied.  37" radial rocker is still getting my savings though.
