In reply to Carless:
I ski both of these boots. I find them both excellent. I tend to pick up the standard Maestrales if the day is more of a skinning / journey day as they are lighter and flex slightly more. Having said that I have skied some steep icy stuff in the alps with them. The RS's go on the feet when its more backcountry / side country and I also ski patrol in my RS's..
If you are mainly looking at hut to hut alps touring I'd think about the standard Maestrales. If your going to skin / boot pack up to do funky steep lines, or charge down the Valley Blanche go for the RS's.
Whatever boot you go for you won't be disappointed.
