hey! a NH guy!! I live over the river in VT. Let me tell ya, I had Cooper Discoverer A/T's on my ex last winter (yeah THAT winter!!) and they were awesome in snow! can't say enough about them. This winter I'm gonna try the Dueler Revo's in stock size. I wanted to upsize, but can't justify the cost just yet. If money is much of a concern, the Discoverers are a great value, I'm sure. My truck came with them already on it though, so I can't say how the pricing is first-hand. Duelers are new and I'm not sure how they do in snow, but a proven snow-worthy A/T tire is definately the Cooper, believe it or not!
EDIT: I've HEARD...that Pirelli's are basically a joke when it comes to snow, by the way...and I here this winter will be worse than last!!
