Check out the new General Grabber AT2's. They look like a cross between a mud tire and AT. Also, look at Cooper's new Discoverer STT with siping. I had the same dilemna and solved it by buying some almost new Kumho MT's very inexpensively. I still love my REVO's, but they aren't of much use in the mud, as they cake up. When my Revos go, I'll either get another set and keep swapping my Kumhos, or go with a "mild" mud radial tire that has good road manners and is better than an AT on the trail. Again, it depends on what aspect of peformance is most important to you.
