Anyone with experience with the Aarn natural balance pack? Likes? Dislikes? - http://aarnpacks.com/products/natural_balance.html
I have the featherlight freedom and love it. However I figure I need a bit more space for my upcoming trip. I'm a huge fan of the Aarn packs and it would take a whole lot to convince me of another brand. Other options are their stronglight category.
While they are bit of the heavy side compared to a few other options (eg. http://www.backpackinglight.com/cgi-bin ... kpack.html) I've experience the flo-mo system and it works very well with my back injury.
