Well I don't have a Crumpler (although they're on my wish list!) But no matter WHAT bag I have, I find that I can never fit my things in there exactly as advertised. Oh sure, I believe my bag *can* fit three lenses and a flash and my camera and my filters, but who has the time to carefully push and prod and flip and stow and shove EACH DANG TIME she wants to get out a new lens? The things fit in there like one of those stupid little brain puzzles and I don't want to solve it every time I put my camera in and out! I like a BIG OLD BAG into which I can fit everything with room to spare. So personally I'd go with the bigger one. That's just me, though!
