Great first hammock! you should have seen mine
That one can be your hunting season hammock
I definitely want to try the ring buckle suspension.
I'd keep the 60" width. It seems superflous and floppy when you are lying down the center like in the photo but the extra width allows for a nice comfy (and flat) diagonal. At least it does in mine. I actually rewhipped and made my sides a little floppier on my second hammock so they weren't pressing on my head so much.
