I have a new one that has seem only limited use, but this will change soon, especially if I choose to take it on my high country backpacking trip next season. Right now, it's a toss up between it, my Eberlestock and my Badlands. I have used the last 2 packs a lot and just as you will read elsewhere here, they have their pros & cons.
Just based on my limited experience with the Barbarian, I believe that hunt33 probably has it nailed down.
