"If you find yourself in a hole, the first thing you should do is STOP DIGGING "
I had a similar setup- fence post to tree- so I used a 4mm accessory cord as a ridgeline- to keep the sag consistent, then I could pull the straps really tight, so when the webbing stretched my hammock did not get all the way to the ground. Think this might be an option for you?
PS.try a set up with the head end on the fence, then you can move the foot end up the tree to allieviate the scoonching up and down..
3) Get the cinch buckles from Paul at AHE.... they are the best I have seen.
I have an ENO single, unknown (maybe a travel hammock) private label made for Alabama outdoors, double(width), and a DIY double layer. They all lay differently. With the single and double I like a lot of sag, I guess about 30* angle. I tried hanging my DIY and found it was very uncomfortable with that much sag. The last time I was out (chinnabee silent trail) I hung it 23' apart, about 7 1/2' up the trees, and as tight as I could get it. The flatest lay I've ever had in a hammock. I had my noname double with me also and tried to hang it the same way and ended up on my back on the ground, one of the metal "S" hooks snapped in two, I was only about 18" off the ground so it just hurt my pride. But I did have that quick response of looking around to see if anybody was looking. I was using the ENO slap straps at the time.
A rainy day spent in the hammock is better than a sunny day at work.
