Not to hijack the discussion away from foils (I'd love to try out a Peak too) but I love the old 15m Flite on snow. On water I haven't had as much success staying upwind but on snow there is more range, especially on steep terrain with upslope winds. I like a kite that turns quickly and loops. I can't seem to make the race type kites do well in junk mountain wind and my 11m foil seems gutless until Beaufort 5. Getting the Flite turned so many light days into fun days. A friend also says the same about the Fat Lady. I think one's performance criteria will influence kite type.
I am really looking forward to winter! Summer winds have been lackluster. Some accumulation way up high will mean kite days wahoo!
I think you should try the Peak asap. There was a good review here a few weeks ago that I think was very good. I realize that no kite does everything perfectly, but for touring back country and most other applications the Peak is awesome. The only thing it does not do is boost and glide like a big twin skin foil or LEI. But sometimes that's a good thing too. And the price is pretty sweet too.
