I would like to hear the answer to that question as well.
I've never personally used the pack you speak of, but for a lot less money a used Dana Designs Terraframe is very very hard to beat. If you can find one in decent shape for under $250 it would be well worth it. In the last three years I have thrown some extremely heavy weights at this pack and it has worked flawless.My only complaint is when wearing it in the timber or brush the top bar catches on stuff.
