If the trees are close together the excess can just hang down.
Perfect, that is exactly the solution that I was thinking of to a problem I misunderstood and thought you were talking about
so you should be great then.
Now what attachment method on the tree end?
I like a simple micro carabiner
(or Dutch hook
, or Dutch ridgeline biner
, or what have you) on a locked brummel or dead eye at the end of each line.
You could tie a siberian hitch or a dozen other knots or hitches but the small amount of added hardware more than makes up for itself in simplicity IMHO.
Let us know what you end up going with.
