I have about a dozen Petersons but only one P-lip stem. I enjoy it as a change of pace, but I prefer the fishtail bits. Peterson has a strong identity with its shapes and designs, the heft and sturdiness, and in general they live up to the appearance of durability. Somehow I evaded that stretch when there were quality control problems. I've always stuck with the middle-priced pipes with the simpler airway design, so that may have saved me. That's a good looking pipe. I have a B10 briar Calabash with that knobby rustication, and I agree, it's a little conspicuous at first, but is enhanced by wear. It's a nice tactile finish. It's grippy.
