I agree with Chef Willie, I would be leery of a truly wild hog. The farmed "wild" hog are much safer.
With that being said, cooker her like a pork butt. Take it to 200-205 for some pulling. Truthfully, you won't have much meat on such a small pig.
It comes down to do you want to tend fire or set and forget. With a guru, the G2 is pretty close to set and forget. The Lang requires tending. Depends on which you want to do.
For me, I like tending the fire. However, when I get into vending, I will get a set and forget for consistency of product.
