In reply to TobyA:
I really like the Vector, but to be a really good "crag sack"... it is still missing a few things.
Ice axe loops / attachements would have been nice (I rigged something myself, and it seems to work ok).
For majority of the climbing I've done over the years (except long multi bitch things). The Vector and/or my small haulbag have been more than enough. Both have their pro's and con's, but in my opinion such sack (or something similar) are really good for majority of users.
Naturally for alpine adventures and up & over stuff I have a "proper" climbing sack (BlueIce Warthog 27 or old 'Ryx Cierzo). But for quite a few multipitch adventures, I've also returned to the bottom. In which case I might carry a smaller lightweight sack for the actual climbing portion, but still lug most of the stuff in the haulbag/Vector to the base (and stash it there, together with some extra stuff, like food etc.).
