Yep, stage one open maintains your rearward visibility. Unlike Arch, I find the cabin to be less breezy with the top completely retracted though. To me, the air seems more turbulent in stage one open. Call me crazy.
I believe a taller person wouldn't have as much of a problem seeing over the retracted top. I'm short. I
readjust the mirror and sit straight.

That seems to help. I don't like not knowing if some fool is riding my bumper.
