The single change I'd make to all Clarks -- I have enough of them -- is to tie a short piece of adjustable ultra-lightweight elastic / shock cord between the peak of each hood and the near end of the hammock. That way, your netting doesn't have to droop whatever way you hold it up, including a straight, vertical hang from a ridgeline. A feel-good DIY reversible customization. In this pic the elastic cord is in the center. Its effective length and so the elastic tension is adjusted between thumb and forefinger by two any-idiot-can-make-them-but-only-a-careless-person-will-not-look-up-the-correct-spelling prusik knots tied in loops of waxed thread. They slide and grip the elastic. (Only one is necessary, but I use two because Rip Waverly would likely do it that way, and he is far ahead of me in the woods.)
Value and ventilation increases for me when the bug net is well away from my face, no matter how I turn.
If you can't zip up the bug net pretty easily, you are so away from the maximum comfort zone, you should put more sag in the hang.
OP is new: Past posts should be perused.
