I am in the market for a lightweight 2 person tent. I am 6ft 200 and she is 5'10 140. I have looked at a few seedhouse sl2 which i have an sl1 of and really like it, copper spur ul 2, and similar but cant really decide on one. Does anybody have a recommendation? I want to stay under 4lbs and prefer it to be a tent with vestibule. thanks
