I think some folks like myself have posted about issues with Peterson’s because they are genuinely seeking advice from more experienced pipe smokers in an effort to become informed on what is or isn’t kosher regarding pipe construction, it’s not always a bitch fest. The fact that we have to question this in the first place probably says a lot, but regardless... I will say that my Pete’s that have gurgled or otherwise smoked weird initially have actually made me a better pipe smoker. When I first started, I smoked way too hard because my pipe (a Peterson System Standard 313, I might add) would take it without skipping a beat and I didn’t know any better.
My Peterson’s that won’t take a rip-roaring smoke without gurgling have taught me to be more restrained and thoughtful in my approach to smoking, and have been invaluable to my learning experience. Now my pipes rarely gurgle, and I’m grateful for the knowledge I’ve gained by working through the minor issues I’ve encountered with them. I think you can find duds with every factory made brand... so if it speaks to you and you enjoy owning it I say figure out how to make it work for you and smoke that shit up. I agree that they are love/hate pipes, and some of them aren’t perfect, but I smoke my Peterson’s proudly.
