I suspect the bulk of people who've got two dozen or more (Tim, myself, Shortrod, I'm sure others I'm not looking back for) are all sort of the same: We received them from someone along the way, or maybe bought "junk" rods when they weren't called "vintage glass" or "blue collar bamboo."
And I'm willing to bet most of the people in that category have a couple they use reliably, and a couple we try to use for "reasons." Shortrod might be the exception with 22 in one season... Shortrod, you might have a problem. 🙂
At this stage, I have a couple I go to reliably, a couple of niche rods that I goto when I need that purpose and a whole lot of weird things, experiments, or acquired through odd ways and never really use.
edit: I went back to look despite saying I wouldn't. Lestrout is, of course, the exception being a collector. I don't doubt your "hundreds" and I'm willing to bet 90% of them are classier than anything I've ever touched. You and Shortrod can probably start a support group.
