I know there are lots of posts on this but they seem to be old like 2014 and I know Kuiu re made their pack systems in 2017 and I'm considering upgrading from my $100 alps commander pack to a real quality elk hauling multi day pack so my question is has Kuiu worked out all the bugs or is there pack still middle of the road like it was? Also if I dont go with Kuiu I'm thinking of getting a SG 3300 solo on the Xcurve frame, is this their most comfortable frame and lightest?
