Well I hung my tarp for the first time last night it was windy and rainy about 38 for a low. I had 40 ft piece of shock cord that I used for my ridge line. I tied one end off and ran the other to the second tree tied a figure eight on a bight and atached it around the tree with a stick. After I staked the ends down my ridge line was sagging real bad. I switched to 550 cord for the ridge line. It seemed to work better. Is shock cord too stretchy for a tarp?

I also ended up with quite a bit of water getting on the foot of my hammock. None at all inside would this have been running down the ridge line? I did not use a drip line but had the tarp tied to the ridge with prussic knots.

Any ideas on how to improve my tarp pitching skills?
