I didn't see the scarf setup, so can't compare this to that. But, I think the weak point is going to be the metal clasps integral to the leash. They were engineered to hold a dog and the load a dog puts on them. I assume you weigh more than your deceased dog. Sorry about your dog, BTW. The nylon will probably hold. Most likely the carabiners will, too, unless they're those real crappy ones sold for only holding keys. Are those real carabiners, like those used for rock climbing?
