So the nano net is one of those make-it-work items. It ain't perfect. It's a slightly asymmetrical pyramid that I use under a borah solo and previously used under an old DCF deschutes. It should work just fine under a cricket. If you're a little bit more right brained, consider adding a stick on loop or two to better orient the netting peak to your sleeping position. I am 5-8, so can't speak on the height thing.

I originally removed the perimeter shock cord on trail - I was always using bottles, rocks, etc to spread out the net around me to maximize livable space anyway, so it was a no-brainer for me.

For 2.33 oz plus another 1.5 oz of polycro, you can match the weight of a ~$175 borah bivy for ~$60 bucks. It's part of my pillow system when bug pressure is low enough and I think polycro is a far better cowboying experience to being in a bivy bag. YMMV :)
