SmoKen,
I'm going to have to call you out on this one
I don't think pork has much flavor at all.
Everyone I know agrees, that's why we rub, marinade, inject till we're silly. Think of pork loin, pork chops. Pretty bland --- UNTIL you add the flavors. Creating a good rub on the outside.
Now, having said that, a good rib with good smoke has a special flavor, but it's the flavor of the smoke that's giving it the taste.
SFENT.
You might think about a good mop during your smoke. It's one way that you can add some flavors that you control without overpowering it. The SE US has lots of places that sell ribs that are basically salt/pepper and mopped, sauce on the side.
If you go for wet ribs, like it was suggested, keep it towards the end. If you do it too early or too long, some of the sugars in the sauce might blacken too much.
