My boy and I are both tired of tying up our Hennessys manually and we think that Dutch's whoopie hook setup looks like the way to go but it gets spendy when buying for two. We got our HH with the 1.5" x 8' long tree straps and I'm wondering of the following would work:

Could I get the $36 whoopie hook + 6 foot whoopie sling + continuous loop package and larkshead the whoopie sling to the tree strap loop and then pass that through the loop on the other end of the tree strap? This would eliminate the Dutch Clip and Dutch Tree Straps saving almost $30 each for both of us at the cost of some convenience and weight.

Would that work? Thanks!
