Whenever these conversations pop up (here and elsewhere) I find it often depends on geography and lifestyle.
I live at the Western edge of Mountain time. In fact not just an "edge", but a big protrusion into Pacific time. In a sane world I would be in Pacific time, at which point I wouldn't care which they chose, as long as they stuck with one. As it is, today sunrise will be 0814. That would be 0914 in daylight time. Too much morning dark for me. Plus I'm an "early to bed, early to rise" guy, and I hate it being broad daylight when I hit the rack at 2130 in July.
So for me, because I'm a traditionalist, and because of where I live related to time zones, I'm a big "standard" proponent. If they moved me to Pacific time, I'd still be in favor of standard time, but could live with all year DST.
