The Silent Armor is more a road tire out of that list. I had both the Duratrac's and the MT/R's. I really like the MT/R's better for the trails. A lot of mud in my area though.
From your description, I think you probably be better off with the Duratrac's. They handle well on the trail and are a better road tire. They have a softer side wall and are light weight. They will be a good fit for your needs 285/70/17's
But if you really like the aggressive MT's of the MT/R's here is a pick of mine when I had 19/60 setup with stock 17" wheels and 1.5" wheel spacer
