Yep, thank you.
If it werent for the fact the tubing looses its elasticity in extreme cold, I think its an excellent solution.
The SC I tested can achieve the same amount of tension as the green thera band.
But Im finding that between 4 and 6 pounds of tension is enough.
And with 1 vesion of 1/8 shock cord putting 4.3 pounds of tension on the tarp, the weight of the tie out is 6 grams. No knots, no hardware.
