I have a fanciful theory about why I have not had quality control problems with my Peterson pipes bought over the past twelve years or so, maybe eight of them. (I fear a serious pipe census that will reveal the severity of my PAD.) I think my luck has been that I have never busted my bloomers going high end but always bought middle and low end, and secondly, that I have bought all my pipes new from big online retailers (mostly Forums sponsors) who may have a little leverage in buying the pipes wholesale, and who may have a better staff informal quality control. I haven't bought any system pipes, and I have only bought one P-lip. This is all magical thinking, but I have had better than average satisfaction with Petes. I love the slightly bulky but nicely designed (to me) look of the pipes and the way they feel substantial in hand, whatever the size. If I'm a little too cheerful about the Peterson brand, that's the reason.
