pitch it extra tight to begin with, and then if it loosens a little overnight, it will still be tight enough in the morning and won't have sagged, with no need for elastic tensioners at all.
I was typing my response/questions to shug so I didn't see your response until now.
I was only planning to use shockcord on the pullouts not the main tarp tieout, like shug demonstrates in his video. I kinda like that idea for reasons he states. For the tarps 4 corner tieouts the plan is to use a none stretch line like amsteel.
For the ridgeline or "no ridgeline required on the superfly" like you stated in your email. I really like shugs idea of using the prussic knots, which should slip and possible save the tarp from heavy snow load damage. I'm a sound sleeper, once I get tucked in, waking to tap the snow off my tarp might not happen. So I'm trying to make my tarp as bullet proof as possible.
A short side story and why I seem so paranoid with snow loads.
About 15 years ago I was in the Indian Peaks Wilderness Area, on a 6 day 5 night flyfishing trip over Thanksgiving weekend. It started snowing about about half way up the trail and snowed for 5 days straight. Back then I was using a large fishnet hammock, ensolite pad, -15 down bag and 8x10 blue tarp held up with 1/4" nylon line. It was not unusual to wake with 6-8" of snow on the tarp.
By day 3 we had 3' of snow on the ground and when we packed out the snow was 3 - 4' deep for about the first mile. Very scary now that I think back on it.
That said, I can't wait to do this again but with much better gear.
