Herr Jugs gets another vote from me. Not that I would not recommend FAST either because I've heard nothing but good things about their work also. I sent mine to Kevin and have 0 regrets.
I mostly ride trails too and he did an aggressive trail /dune port on mine. I have a 4 mil long rod stroker, custom cut 20cc domes in NOSS head, + 5 timing, .020 over, v3's, pro flow filter with no lid, and PC pipes. It is an absolute beast in the woods and trails. 110 gas is a bit pricey though.
Call either Jeff or Kevin, tell them what you're looking for and they'll hook you up with the best port for your riding style.
