i guess the only way to resolve this is to try again and see "how low can you go" i really thought somebody would go out in their yard and try to see what vacinity the lowest angle is with re-tightening, oh well. i'll definately try it at some point, but you need 2 people and the right trees so i don't know when i'll get a chance, but i just don't think really low angles are possible.

well, i see where you're coming from here. for a short span of time the angle is much less, but considering the extremely low weight/force it takes to "drop" the hammock to a much higher angle, i don't see how it would be more force than it is after the hammock is fully weighted. for instance when i pull the suspesnion horizontal, i can pull on the bottom of the hammock with my hand and get it to drop most of the way with very little force. you could probably go from zero to 15deg by throwing a good sized book in the hammock, yeah it's multiplied by a larger number at that angle, but the suspension only holds a tiny fraction of bodyweight at those low angles so it doesn't seem the overall force could be as high during the "drop phase" when your feet are still on the ground holding the majority of your bodyweight.
"It isn't difficult to go through the geometry and force calculations to see how much stretch and drop you get for particular sag angles when you started from a near-zero sag angle (this assumes it is all stretch of the suspension line), I have done that before. For instance, for a HH ULB at a 12 foot span, all it takes is 0.8 inch stretch on each suspension line to get the hammock to drop 5.5 inches and you end up with a 14.5 degree suspension angle that represents 2x the users weight on each suspension line. At a 20 foot span, it takes a 2.4 inch stretch on each suspension line to get an 18 inch drop with that 14.4 degree suspension sag angle."
anybody know who has the best deal on cinch buckles?

dave, i just ordered a yates screamer. basically a shock absorbing webbing device where some of the stitches rip at a certain point to absorb shock. the one i got activates at 2kn with an accuracy of +/-5%, so it should activate roughly somewhere between 420# and 470#.
