I'm moving to an eberlestock. I don't like the way the Cabela's lashing system works with the shelf system- used one last year to pack a deer out - puts the weight and center of gravity on my lower back. My buddies use Eberle's or Badlands and they like how the weight rides closer to your mid/upper back and the load doesnt move down or shift around or require alot of lashing. 3 straps, rifle in the scabbard, then go.
Having both hands free is a big plus - esp if you are by yourself packing out.
