No, no. I wouldn't dream of telling someone what gear they should use. Although I am curious what quilt you're carrying that is 3 lbs. Is it a snythetic?
My Rocky Mtn. Sniveler is only 28oz and it's a long. My Winter Yeti is lighter, I just haven't put it on the scale recently enough to be able to remember. But, I can guarantee that it's nowhere close to 3 lbs.
Curious minds want to know.
