Judging by the exchange on another thread, I think she is probably gone now, so we most likely will never know.

I have been tempted several times over the years to buy an Ursak thinking I'd use it sometimes for backpacking, canoe camping, and maybe even possibly on a tour sometime. I always balked when I priced them and dug into the specs and looked at where they met and didn't meet canister requirements. If they ever got National Park certified across all the parks, I'd probably spring for the 10 liter one.

I could imagine wanting the capacity of the XXL, but only for a canoe trip where I could take both of my canisters and a 10 liter Ursak if I wanted to. On a road tour any of the canisters or Ursaks are bigger than I'd ever need. Maybe on an off road tour I could possibly need to carry more, but probably not. Backpacking I am getting to where I doubt I will ever again want to carry more than the BV450 or the Ursa Major (10 L) will accommodate. I can manage 5 days with either of them with careful packing. Beyond that I'd have to rely on resupply by some means.

At 7.65 oz. for 10+ L of bearproof storage the Ursak Minor does sound tempting though, saving saving over 2 pounds compared to the BV450. When you add 9.2 oz. for a $40 piece of aluminum, it gets a bit less tempting. On the other hand I do have some 0.025" aluminum sitting around so I could probably save that $40. It is from an unknown source. so it isn't as hard as T6, but it isn't real soft either. It would still weigh the 9.2 ounces though.
