Great post! I have been thinking about this thread for a while, and have come up with what I believe is the right answer for me - YMMV.
I have "sets" of pipes.
I have "collectors", those pipes that for whatever reason I don't think I will/can ever smoke (can't be repaired to smoking shape, they have never been smoked and I can't bring myself to smoke them - they've lasted this long, they are so old it is amazing they are still around so I don't want to damage them, whatever) so I appreciate them for what they are, art pieces. Less than 20 of these...
I have "smokers". Those that I smoke regularly because I know they smoke great, I like the shape, etc. These tend to be Peterson 306 & 304 because I like the flat bottoms. I also have some billiards (generally Peterson 106s - though I just sent a message to
@Notow1 to see if he can work me one up), since billiards are the only shape that fits in my travel kit worth a d@mn, and I travel monthly. I have around 10 of these...
I have "beaters". Those that I like to try new tobaccos in. These are generally pipes that are decent smokers, and because I smoke them regularly trying new blends, I don't worry about them drying out, etc. I have 5 of these...
I also have "Parts" pipes and future resto pipes that I intend to get to when I retire (4 1/2 years away or so) or when my side job slows down, or when I get the right tool, etc. I have at least a dozen of these...
Maybe I too am suffering from some form of PAD? Ugh, another affliction as I grow older...lol
