This just occurred to me: You do pitch this tarp on the 11 foot ridgeline, right? I'm not intending to ask a dumb question, and I'm sure you most likely do that, but the JRB 11x10 is designed to be hung on either the 10 foot "ridge" or the normal 11 foot RL with the seam. Obviously, if I decided to hang it on the 10 foot length, it would probably not be long enough for my Claytor and the extra length needed for the cinch buckles.
I wish you luck on getting it to fit, because I have really liked this tarp.
For I consider that the sufferings of this present time are not worthy to be compared with the glory that is to be revealed to us....that the creation itself also will be set free from its slavery to corruption into the freedom of the glory of the children of God. For we know that the whole creation groans and suffers the pains of childbirth together until now.
