Re: I think I did it!
You can tie a taugh line hitch in place of the square not to give you something more adjustable... just tie the loose end of one cord to the other cord as if it was wrapping around somethint and back on its self. Tie both ends and it comes out pretty clean.
I will say, all said and done... Whoopies or synch buckles are probably a better solution.
I tried doing a bunch of knots and cord setups and what not at first too...
Even thought structural Ridgeline was pointless, ect... had super easy setup that was very customizable in the ropes... Ended up going whoopies for weight, with a seperate adjustable ridgeline.
So much easier. Tighten one end, then the other... done. Much lighter and simple. Kicking myself for trying to re-invent the wheel when thousands of people had already blazed a trail. Sometimes following the masses is wrong but when everyone is doing it one way it may just be that after the collective failures and successes have been put together they find something 5hat just works. Obviously fiddling has its place though if no for reason other then entertainment and creativity... Just trying to point out that sometimes we get so hung up in trying to find our own perfect solutions that you miss something else that has been developed into something pretty good...
