I have some fabric that I just got to try one of these. Any thoughts on using 4 pieces of shock cord, both sides foot and head end? Then it wouldn't matter which way you layed, you could adjust it. You would have a weight penalty, but if it didn't work, then I could remove 2 of the shock cords and lose the weight.
Anyone try this? I usually lay one way, but would like the option to lay the other.
