What's so great about shifting being deterministic? Do our gears not deserve to have free will?
I haven't used teflon cables for shifting yet, but I do like them for brakes. I used bulk brake housing for my shifter cables when I last overhauled my mountain bike. It's steel on steel, like you said, and it does feel pretty snappy. I want Aztecs though, those look awesome.
