You're both getting near the mark, canotrouge and memaquay. I chose convenience and comfort over tradition. I'm not intending to pick any fights here. This is just my view. An ugly rubbery dry pack tricked out with suspension harness keeps my stuff nice and dry, and me nice and comfy when carrying it. That's important to me. Likewise the barrel works nicely too. The same reason I chose an "ugly" asymmetrical "plastic" canoe. Light and inexpensive= convenient and comfort. It's not for everybody. I picked this stuff for me, and me only. The trip is all about the experience. Suffering is not what I have in mind for a tripping experience. Bugs? I'd rather find ways of eliminating that discomfort. Cold? I try to prevent it. Wet, wet, wet? I can put up with some, but don't want to come home completely puckered up like I sat in a bath tub for 5 days. Pain and strain from physical exertion? I like some exercise, but I'll not punish myself for the extreme joy of extreme discomfort. I try to pick the gear that'll save me from the worst of a trip's discomforts. That's just me, it needn't be any of you out there. We all make our choices. I like learning of-from others.
memaqauy, I just checked the price of my SealLine pro, and it now tops 200$. I paid 165$ a few years ago. I still consider it a deal, but prices keep going up and up. It won't be long before a couple garbage bags in an old canvas pack will look real good again.
