Larue OSS

After watching the advertisement I'd be inclined to buy a padded VTAC sling and save myself a couple of Jacksons. In my mind, if you have poor fundamentals and body position the rifle will probably still do what you don't want it to do, regardless if you have some new fangled sling wrapped around the bipod legs.
 
It looks like several gimmicks tied up in one package. Issue I see is wrapping the sling around around your upper body (lungs). If your are huffing/puffing, how does action transfer to the rifle?
