Is there an adjustment for the Duplex Timberline belt's angle? There are two angle straps on each side at kidney location. If I unhook the bag and rehook to the frame the bag dangles. Are the original Timberlines more rigid? Is there a downside due to this? Is there a video tutorial for new/first time users regarding proper setup/adjustment? Don't get me wrong, I have carried many packs many miles. I am just looking for some direction and I will run with it.
