first a bit about me, i rarely do any serious hiking, so weight isn't a major concern for me. i do like a relatively small pack size, since most of my camping is done via motorcycle. i'm 6'1" and my current bag (which says it sleeps to 6'2") is a bit too short. i rarely camp below freezing, i think the coldest night i've spent out was 30 degrees F. i'm also on a budget and don't want to shell out the money for down. so, of these bags listed, any recommendations? any other bags i should consider in this price range? thanks!
