Since none of the bears need to be helping, I guess a maggot may have to step in... (much love all)
I'd go with the aiguille as it's all gore-tex as opposed to the exposure, which is made of conduit. I have the swift, which is essentially a lighter, more breathable version of the aiguille, and it's very resistant to the wet and wind, not to mention extremely lightweight. For an inner layer, you can't go wrong with a windstopper/windbloc fleece. You may be able to get out of it cheaper with an EMS fleece, which are extremely durable and very warm (I've been wearing mine constantly for 8 years or so). If you're one of those people that gets cold really easily, you may want to consider the MH flip jacket as an inner, as it's a very form-fitting synthetic down jacket that is warmer than anything else it's size IMO. Also, midweight bergelene is key to surviving the cold.
