If it "fought me" going slowly in a parking lot (steering with hands rather than hips at that speed) is that bad?
How do I tell tension from the cables from wear in the headset?
Flossie does these things, Commutermobile doesn't. But Commutermobile has huge loose floppy loops of cable in front, and Flossies are streamlined and fairly snug.
Sounds like your headset could be worn. It's usually the fork crown race that gets a little dimple where each bearing sits, so it likes to stay there and will behave as it it's spring loaded and want to go back to straight ahead when you turn it slightly. If it behaves that way on slight turns, it's the headset and not the cables (but make sure the cables have enough slack to turn at least 30 degrees before they start to tighten). I assume Flossie has a 1 inch threaded headset without sealed bearings. It could be that the headset is a bit tight, and that will make the spring-loaded feeling worse. So you could loosen it a bit and see if that helps. But don't loosen so much that you get jiggling noises when you bounce the front wheel on the ground. You can still ride this bike safely as long as the spring-loaded feeling doesn't affect your control. You can get used to it like that and hardly notice it (but you'll notice when you swap bikes). It's usually caused by riding with the headset a might loose and hitting a pothole. A notched headset should be replaced sooner or later. Let the LBS do it - takes some expensive tools to remove and install crown races and head cups, and the spacer thickness has to be correct.
Oil is good, grease is better.
