Funny, I read this far along in a thread, and I get to here, and totally have forgotten what the OP was. Oh, pipe shapes... I really don't care much for bent droopy, flaccid pipes. I do have some, but I don't grab for them often, maybe a blue moon. a quarter bent is ok, but straight and randy is the image I want to project, not all tired and not up to the task.
Most of my pipes have been dublins and bulldogs, with the occasional topper in the bunch. But, I've recently started collecting billiards. I wasn't impressed with them much in the beginning. Too square, Father Knows Best for me, but recently I've come to appreciate a 1950's dad pipe.
