I didn't have this happen in my hh, until I added some straps. A twist in the straps took care of it.
Try this, hang the hammock, then take some water and pour it down the suspension line. Watch what happens. That should be the worse case senairo (next to death) for the water running down the support lines. If it stops that you will be fine.
Is that too much to ask? Girls with frikkin' lasers on their heads?
The hanger formly known as "hammock engineer".
