IROKS hands down. Since I'm up in your neck of the woods and do a lot of the same wheeling that you do I can speak from experience that the IROKS are the best all around tire if you aren't driving on the street. I was just down at browns camp a couple weeks ago and it was raining the whole time there. MUD MUD and MORE MUD. Needless to say that even when it was freakin slick the iroks hooked up still and did awesome. Now in the snow I don't think I have ever seen a tire do as good for a multi use tire. All of the snow wheelers where i live swear by the Gumbo Radials but after a few guys have gotten the iroks most of them are now switching over to the iroks. To compare in the snow, my buddy had some 35 MTR's and he could not keep up with the iroks. Also in the rock, my experience with iroks rates up there with my red label sticky Krawlers. They are the closest I've had traction wise in the rocks for a DOT tire.
Its just my 2 cents but I thought i'd through it in there.
