When you rig a doubleline pull you are halving the effort required for the pull, but trading that against distance and time.  But, it's never exactly half, or a perfect 2:1 mechanical advantage. Energy is used to rotate the pulley, and also to form then deform the rope as it goes around the pulley whether that pulley is a snatch block or snatch ring. 

But how much energy is lost? Do you end up with a 1.99:1 advantage, or 1.5:1? And what of the new snatch rings...are they really so inefficient they can't be used?  Watch this video to see the results of realworld 4X4 testing with three snatch blocks and six snatch rings...the definitive answer!
