Thanks for the great review, angrysparrow, and especially for the detailed pics. That velcro end closure is essentially what I've been doing with my DIY net, and seeing Brian do things that way settles my mind about it.
Re that closure in practice -- did you encounter any problems with the velcro getting separated by motion of the hammock / ridge line?. I have had that happen with mine, but wonder if it wasn't because I use a fixed ridge line. I suspect it might not happen with that shock cord. FWIW, if it does happen, I found you can keep the bugs out if you stuff the end space with some balled up scrap netting, held in place by the velcro.
Nice product, nice report!
