Watched my shifting get snappy after 3 hours of cable friction hunting

Had this old Trek 520 that shifted like trash for weeks. Figured it was the derailleur or the shifter but nope. Finally pulled the housing and found a tiny burr inside where I'd cut it too close with cheap cutters. Filed it down, new ferrules, fresh cable. Night and day difference just from that one fix. Anyone else waste way too much time chasing something stupid like this?

I mean, that specific burr thing has never bitten me, but I've definitely spent whole afternoons chasing ghost friction only to realize I just needed to reroute the cable over a different guide.

chasing ghost friction" is such a perfect way to put it. I actually just read a thread on another forum where someone was fighting with their rear derailleur for a week, swapping cables and housing, and it turned out the cable was just slightly pinched under the barrel adjuster. Makes you wonder how many of those "mystery" shifting problems are just bad cable routing in disguise. Have you ever tried the trick where you zip tie the housing to the frame in a few spots before you cut anything? I heard it helps you visualize the natural path before you commit.
