"yesterday is history, tomorrow is a mystery, but today is a gift---thats why its called a present" - Master Oogway
It's always best if your an early riser!
First time I used my hammock with the rings I forgot to tie the half hitch safety knot and did indeed end up on my butt. Rather embarrassing, as this happened in front of my ground dweller river buddies who were already giving me crap about my hammock. Once I remembered the half hitch I was fine with no slippage. I saw this system on Grizz and Shug's videos and thought it seemed pretty easy & quick. I've never tried anything else.
If you already have an amsteel loop on the end of your hammock, the cheapest and lightest option is tying a slipped sheet bend or something similar between the webbing and the loop. Its free and weighs nothing. Just a thought.
Don't let life get in the way of living.
One point in favor of the Onrope buckles is that they are rated for life support...that makes me all warm and fuzzy.
It has always been my private conviction that any man who pits his intelligence against a fish and loses has it coming.
