Not sure if i've watched that video? lately, i've been removing all my body-grip chains, just seems like a waste, not to mention all the darn things tangled. i don't use many body-grips, but it's easy to just pull out a piece of wire, after 2, 3 or 5 catches i'm done in the area anyway. except for high-water, i've never lost one.
a few years ago, i bought some 120's that had about 4 feet of 5/64th(i guess)cable on them with about 18" of tie wire on the end, honestly, by the time i un-roll all that junk, i could have set the trap and moved on. just my 2 cents.
