35" BFG all terrains?

[Huck BB62]

Well, the stock tires are shot and I'm looking to upgrade. I commute in the twisties (hence the reason the stock tires are shot at only 20k) What would be the choice? 33" MTs? 33" ATs? 35" MTs? or 35" ATs? I'd like to hear the comments on why or why not. Would the 35" MT or ATs kill my mileage? How about handling? I run hard up and down the mountain everyday but need the H3 to do well offroad still. Is there a perfect tire? I'd like it to handle like a low profile Pirelli on the road and perform like a MT off road.
