I have 6 or 7 p-lip System pipes and I like them very much. For the most part they are quite small, with fairly small bowl dimensions and a couple that are huge. I use the small ones for high Vit N tobaccos like Peterson Irish Flake or Dunhill NightCap. I find that the small bowl AND the p-lip system seems to make me able to tolerate the nicotene hit better. I really love the flavor but not the effect. I'm not a big fan of the room-whirlies. Great pipes, fishtail or P-lip, you'll probably still get a good smoke out of either!
