Since GigaMike pointed me to the Black Diamond Firstlight, I've been reading some reviews about it online. I think it would be a perfect tent for me for snowcamping in the Sierras. I love its light weight, but seems like condensation could be an issue. I guess it's the nature of single-walled tents... Is it something I should worry about with my down bag getting wet? I imagine if I go solo, the 2-person Firstlight provides ample space so I won't be up against the sides... I also read that the internal poles are more conducive to dripping (from condensation)? Anybody has any experience with it? Any favorite 4-season tents that's still light weight? Thanks!!!
