One of the first pipes I bought was a churchwarden, largely because of the mystique and stereotypical associations it has with luxuriant relaxation, and partly because, practically, it's supposed to cool the smoke.
I must have bought a subpar one, because the bowl burns hot, but I never had a good smoke from the thing. Every once in a couple months I'll take it out and give it a try, but it never fails to disappoint. It's actually more of a pain to use, for me, than a regular pipe, and its false promise of relaxation only increased my irritation.
I seemed to have gone towards the other end of the spectrum, and now have something of a penchant for quite short pipes.
