All I'm going to say is that - after experiencing about a decade of living in AZ and not worrying about toggling time - I'd still be in that camp that support permanently choosing a time.
I live in Arizona as well, and agree. I'd rather everyone else just pick a time and stick with it. Preferably DST so I can be 3 hours back of the East Coast and get 3 hours at the end of the work day there for solid working while no one else is around. And I like having sporting events on at the end of a work day.
