as you can see, the attachment heights go up pretty quick as the trees get farther apart. some of those heights are for less than 30 deg angles. i'd say i often hang at 30+ deg. it's hard to tell the actual degrees your lines are at, but when the rl sags when you sit and tightens when you lay, it's just about perfect. it can defiantely be tighter than that and still be ok, but i think if you shoot for that whenever you can, you'll learn what it takes to get a comfortable hang pretty quick.
