Nothing wrong with a soft shell, but I prefer the gore-tex pro. nice and light, yet waterproof/breathable. on colder days wear a thick fleece, on warm days, by itself.
Here in Whistler, it generally stays pretty warm (around -5) so a down jacket is overkill. buy anything but a down jacket for Whistler.
why sticking to Burton??, imo they are overpriced junk (fine for 1 season, but not built to last). companies like arcteryx,north face, patagonia all produce much better quality stuff (still expensive though)
