i've used the stuff a good bit. you can use a larks head on the end of the hammock.
while a double sheetbend slips when tied to raw hammock fabric, tying the single braid dyneema to your tree straps with a slipped double sheetbend works great, and i've been tying directly to a single steel ring on the end of a tree strap with a slipped buntline hitch with great success.
we are talking about 2 different setups here. a larks head can be used to quickly connect and disconnect line from the suspension point. the suspension point needs to have some sort of ballish mass to jam in the back of the hitch though. the mass can be created a number of ways. standard whipping, cinching and tying off a threaded hem, zip tie etc., but the sheetbend method does not require this end mass, you are tying the fabric and the line together just like if you were tying 2 lines together.
