I have yet to find a booar or sow that wasn't just fine on the table and we've killed some big ones. The brine recipe beaunaro mentioned is nothing fancy and has been around 800 years or so. It works great on all pork.(google: brine for pork)Just don't let it soak too long in the brine mixture, 24 hours max. It speeds up the cooking time and helps keep the meat moist.
I shoot the 50-100# hogs, more tender.
That said, I imagine pigs from one environment would taste different than from another. We hunt citrus groves mostly, the pigs grow up on citrus, whole corn, pecans, and acorns.
