John,
I recently got a Condor pack and I love it. I looked at the vulture, but I went with the Condor instead. The pack has no support system such as a frame, etc, but it is comfortable to wear, even when it is loaded down. The Condor has quite a few adjustment straps that I have yet to get figured out.
I posted some pictures of my attachment points in a post earlier in the forum. Look for posts done by me and the title is TIme for a new backpack...Maxpedition Condor.
The attachment system is very easy and slef explanitory.
Good luck, you wont be disappointed by the Condor.
Garrett
