I'm on my second set of 305/70 Buckshot Mudders. I've got no complaints at all, and I made the switch from BFG's to Maxxis. Was real happy with the BFG's, but the Maxxis, as you said, are considerably cheaper. I went a little over 50K on my first set of Maxxis, which I thought was extremely good for an aggressive mud tire (and the extra weight of not only a CTD, but 400# of pipe bumper hanging on the front). Mine tend to balance relatively easy, and are a smooth running tire. They do get kind of loud on the highway, but a straight pipe tends to overpower the tire drone.
