Just got my chinook 12'x9.6' tarp and did a test hang. I thought that the 1.2 tech line from diy gear would be a good ridge line but I'm having issues getting prusik knots to stay tight. I've attached some pics of my setup.
On one tree I have the tech line with a fixed loop attached to a soft shackle. On the other tree I have the ridge line marlin spiked to another soft shackle that is attached to a presik. I made the presik out of the same 1.2 tech line.
Any advice on how to keep the presik tight? Maybe I should get the 1.9 for the ridge line and stick with the 1.2 for the presiks but don't want to spend the money if there is a workaround.
I've attached the tarp ends to another soft shackle and I made a presik with a small 1 inch piece of arrow shaft that I slip the soft shackle over for quick release or what-not. (the soft shackle in the pics is from cheap parachord. I will make them out of amsteel once I have the setup tweaked)
Maybe a different knot would hold? I'm a newbie for sure so don't know what else might work.
Thanks in advance,
