I've done a bit of cross-country skiing on trails at local mountains, but I'm more interested in getting off the trails and out into the woods. The terrain around here is pretty steep in general with very heavy powder when it snows, which it does a lot (the closest alpine area currently has ~11 feet of snow on the ground and this is normal). Generally, it doesn't get too icy, and rarely below say 15F in temperature.
I'm a bigger guy, so I've found that snowshoeing is pretty painful once the powder gets deep and I lose the ability to "float" pretty quick even on bigger snowshoes.
I have very little interest in climbing things for the purpose of downhill skiing (I'm a snowboarder anyways), mainly I want to move efficiently through deep snow with a pack on, camp, or climb mountains.
I would prefer a solution that is lighter (i.e. if I can strap 2 lbs to each foot and have a somewhat compromised setup, I would prefer that to a "perfect" 5 lb setup).
