Deuter are great! I've been using ACT Lite 45+10 for several years. Can fit a lot into it, even for multi-day trips. Have even done a 4 day winter hike with it, though the packing did get a little tight then with the extra gear. Can even fit climbing gear into it for short summer trips. And it's a light, robust pack. As a result, one of my Berg-buddies now uses the same model, and three others have various sizes of the Air Contact. I would definitely stick to the ACT Lite.
I would demand better service from your Cape Union branch and get them to order what you want, or send it in from another branch. Not sure that there is another Deuter agent in SA.
