One other thing I meant to note from my ride today is that I had never noticed before that the reflectors on quill pedals without cages actually serve a practical purpose. I'm skeptical as to how visible the reflector is when I've got a shoe on the pedal, but what I noticed today is that the weight of the reflector causes the pedal to rotate into a position that makes it significantly more likely that I'll get my foot on the flat side of the pedal on the first try.
I don't know if this was an intended result, but it makes a big difference for me using these pedals without toe clips (which I despise). I installed SunTour quill pedals without a reflector on another bike earlier this year, and I was constantly frustrated with finding my foot on the side of the pedal where it's supported by the spindle and not the pedal frame.
