I wood use Apple wood if you have it. If you have access to any manzanita wood it's my favorite on pork. Unlike shoulder where you want to render the fat a pork loin has little internal fat so if cook to 140-150, wrap in foil and set in a cooler for about an hour to rest it and allow the moisture back in. I like to stuff mine with Italian sausage and wrap in bacon, but a simple pork loin is pretty darn good just seasoned as long as it's not over cooked. Have fun.
Your right DaveW! I switched from tenderloin to loin half way through that replyTenderloin might be a bit small to stuff, but spot on with everything else you said.
