I spent a lot of time and a bit of $ getting various estate pipes to try - as I was learning both my own, and the unique smoking characteristics of various pipes.
During the process, and over about 3 years, I've got some that are my "shelf" pipes; those which I really like aesthetically, hold a spot in my memories, or are simply a nice smoke that I'll use - sometimes. Probably about 15 in total.
I've also got a couple racks holding about 15 or so that I don't really care if I ever smoke again. They're just average, or more precisely, were just average for
my style of pipe utilization. At some point these will likely be sold off, as I see no reason to hoard that many extra pipes, but we'll see.
Interestingly, the division between those two classifications of my personal pipes began to sharply define itself when I began smoking Petersons - especially with a P-lip. Although not all of them are P-lip, I have 15 Petersons I truly enjoy, and 4 more new, unsmoked ones waiting for me to gift to myself. These are my daily tools and are the cause of neglect for all of my other pipes.
As of this week, I could say that I've conquered my PAD, as now, instead of buying pipes, I only purchase:
smoking instruments. We'll see how that plays out over time.
I also have a few artisan pipes that are for unique or special occasions, a couple of them still yet to be smoked by myself as that occasion hasn't presented itself to me yet. (I guess I like to plan ahead.)
So I used to make an attempt to utilize all my pipes regularly, but that has changed, and when I get some free time down the road I plan on sending them off into the world to find their way onto the path of pleasing another individual with their service to our pastime.
All in all I guess I was a bit overly enthusiastic, as the amount of time I have to enjoy a pipe is really rather limited, and my "pipe to time ratio" is really out of balance...
