I use the Bear Boxer and I love the balance of weight AND shape. I say this, because the Bearrakade(sp) might be a few ounces lighter, but the size is not nearly as accomodating(unless there is a model I don't know about) as the solo Bear Boxer (which I have used for trips up to four days+)
PS check out EBAY -- that's where mine came from
I think the Bare Boxer will be the way to go, now I will search for a used one if possible. Thanks
