I'm thinking about switching from my current solo set-up (a Spinntwin / BMW bivy) for one of the shelters listed in the subject line. My reason for switching is mostly for fun, but I have a few questions:
1. Which of these shelters can be used w/o a bivy to keep spindrift off? I currently use a WM highlite or a Arc AT, plus Montbell Alpine Light. I'm not thrilled about getting much moisture on either set-up. If I can get to 11 oz, I can knock a few oz off my current shelter shelter system.
2. Which of these shelters has the most interior room?
3. Which of these shelters is the most stable in the wind?
It's true that the cape could substitute for a rain jacket/pack cover, but I already use the silcoat cape, which is very light and serves both those purposes. I'm really looking at each just for the shelter aspects.
Thanks for the input.
