The ULA Ohm for all my trips up to 10 days so far, which means a weight of ~ 26#. I have carried up to 32# on training hikes up to 12 miles, so I suspect I could squeeze a couple more days out of it if I had to, but I doubt I'll ever stay out that long anymore. That said, at 32# it starts to sag a bit and the last 6 miles or so get somewhat uncomfortable, but still tolerable.
