The Coleman exponent Cadence that I'm looking at is essentially the Coleman Hooligan 2 only smaller and half the weight. That REI sub alpine looks pretty good. Unfortunately my girlfriend might have already bouGht the Cadence. It's a birthday present for me. If she did already get it, I'm sure it will work fine and if not I can always sell it and get something else. If she hasn't bought it, I might try to get that REI sub alpine. The weight looks good and it has good reviews. I mainly just want something that has room, won't leak, and doesn't weigh 6 lbs or more!
