To begin with I'd keep the four Petersons, lol! Honestly, I don't know anything about the others.
I have no idea what any of them mean to you so won't presume to say.
From someone who is hardly a veteran at all this . . .
I just culled out six pipes last week - went overboard with buying pipes IMO over a relatively short time. They were darn nice pipes, I could have kept them and even given the unsmoked ones a chance, but what they all had in common was I just didn't give them much of a look when it came to picking something to use. All nice to look at, but if I'm not going to use them they don't need to be around, and as I've gotten to know what I like I realized they weren't it. Now someone else can hopefully make some good use of them and I really won't miss them. And if my wife sees a couple customs show up she knows the herd is still smaller overall - and, lol, she really doesn't care.
