In reply to StuLade:
I love the AK30, and Crux have said they will replace it with a new RK30 under warranty, but unfortunately they don't have any in stock and don't anticipate having any until May. Still, excellent customer service regardless.
However, I need something sooner than that, and in some ways would prefer a few more features. I'd like a pocket, and one criticism of the AK30 is that the side compression cords tend to compress the top of the pack rather than compressing evenly all the way up - so everything sits at the bottom like a big bumbag when it is half loaded.
