Although the previous chain wasn't stretched/worn out, it appeared to be a mishmash of at least two different chains, so shifting was often a bit of guesswork and hunting. No problems now with the rear shifting. (I need to tweak the front derailer, or check the thumb shifter -- it skips the middle chain ring on down shifts, but it was doing that with the old chain too.)

I was a bit worried about the re-inserted pin after reading some cautions from veteran mechanics about Uniglide/Hyperglide systems tending to put too much side pressure on chain plates and causing links to come apart. I've checked the chain before each ride. So far, so good. But I'll feel better about it after installing a KMC quick link, which doesn't rely on friction. The tricky part will be identifying the mark on the pin left by the chain tool, but I think I can still see that mark.
