Bgdaddy had a warbonnet 1.7 set up at the Nottarally using Kammock straps and I had a chance to hang for a bit. Very nice! Much larger than my modified Hennessey. The Slap Straps that I used stretched bad enough that it took three nights and numerous re-tightening to get rid of the stretch. The idea seems sound but the materials leave a lot to be desired.
