Since I'm retired, no work days, and have one hobby at a time to keep down costs (last one was repairing and adding to guitars), I've slowly accumulated skis - fix, tune and wax em (for me and fam). I especially have liked narrow skis (under 90, preferably 80 or under) and fat skis (105 to 120, currently).
All things being equal, for powder I would have at least two: I would have a good fat ski that has more float (as well as crud/powder chops), in addition to the Sickles, which do it all, but have less float, usually. If you ever decide to test the waters on other 105 plus skis, I'm sure the pugski world would oblige with lists and favs.
Plus, if you have more time, or powder days, it's fun.
