I'm also looking for a backpack, for hiking or BOB.
I'm looking at different brands, Deuter being one of them.
But I want something around 40/45 liters.
I presently have a 30 liters, with a very good waist strap, but it is too small (if you want to carry some extra clothing, that take space !)
And my old 55 liters is too big and not a good carrier for such a size.
My Maxpedition Condor is fine for EDC (computer, documents, a few tools, cables etc.. + PSK + lights). BUT I would not use it for heavy loads and long journeys : the waist strap cannot be used to balance the weight on your haunches; the pack is way to short.
The waist strap is just made to hold the pack close to your back. Maybe with an additionnal Maxpedition waistpack, the Condor can then "sit" on it ... I guess it's designed to be used that way, in conjonction with another pack. Anyone (with a military experience?) can confirm/deny this opinion ?.
