I had a quick look at the photo of your truck the other night. Nice look'n beast (for some reason the photo seems to have disappeared - might just be this computer).
I'm running 33" BFG muds at the moment with a 2.5 OME lift (SUA). The truck doesn't get used much during the week so I was thinking of sticking on a set of more aggresive tires. With a body lift and extended shackles I should be able to run 35's.
I was thinking of going a set of radial claws. They seem to bridge the gap between the BFG;s and the Simex's. I'd be interested in a local opinion.
