I'm pretty sure I'm around the 40-50 pipes mark. About 25% don't really get smoked. My Grabow Freehand is just too damned big to smoke often, a few of the others just don't smoke that great, or have an uncomfortable stem, or something similar going on. The others are because I am a little OCD, in that they were purchased for "backups". I had a line on some NOS Grabows a while back; when I bought one and really liked it, I would buy a second as a backup. As a consequence, I have two old Savoys in regular use, and an unsmoked "spare". Likewise, a Royal Duke bulldog in use, and one in reserve. I mean, hey, really, what if I want to go buy a nice Grabow bulldog in 20 years, and they're just not available anymore? Huh? WHAT THEN! WHAT IF I JUST CAN'T FIND ONE? THIS IS PERFECTLY NORMAL! Oh God, I gotta go check on my spare pipes...
