I bought this pack to be an all around mountaineering pack, whether I'm skiing, or climbing ice or rock. I was really excited for the ability to externally carry gear that I'll need on a climb, then start climbing with a fairly small pack.
Rope Carry: The rope carry is awkward, unlike other blue ice rope carry systems the strap starts quite low down the pack, likely to allow more range for compression, but it makes the rope carry basically unusable. You can't place the rope on top of the brain without it wanting to slide down the pack, and you can't put the rope under the brain if you're carrying a lot of gear.
Ice Tool Carry: The upper tool carry isn't good, I had to slide the tools carefully into the strap, feeding it in. Then on the first trip the elastic came out since it's just a knot that holds it in the hole, so now I just have a loop of elastic that leaves tools flopping around. This is another case where Blue Ice could have simply done what they do on other packs like the Dragonfly.
Side Zip: The side zip is a nice idea, but it is quite hard to rummage through the pack or stuff gear with such a small opening.
Positives: I like the frame, avy gear carry, and skimo style chest waterbottle holder. It is a pretty good volume while not being too bulky or uncomfortable to climb with.
