Any pipe you want to smoke them in seems to be the answer to me. If you're concerned about stank crossing over, just dedicate a pipe to aromatics and have at it.
As an aside, not all aromatics are the devil :evil: You don't have to dedicate a "low end" smoker just because aromatics aren't generally considered "high end" tobaccos. I think most people move on from them as they mature in their pipe smoking more for the sake of tasting tobacco instead of toppings...not because they're inferior. Sure, some aro's are trash, but there are several out there that are blended using good tobaccos and toppings that aren't so intrusive.
