Alright, I've just got back from the garden and I have tested my new hammock. These notes are of course only based on testing it for 30-45 minutes, not what it would be like to use it on a trip, though they do give me a good indication for what I can expect I hope.
I've never put up a hammock before in my life. Not a simple garden variety one, and certainly not an advanced hammock like the NX-250. But, it turns out it wasn't particuary hard. My hanging setup used tree straps and drip rings. Although I didn't try much without them, I suspect they both made the job a whole lot easier. Especially the drip rings made it trivial to do microadjustments of the setup. In addition to being good for the trees, the tree straps made it a lot easier to work with the ropes as well. Pretty much everything that needed to be adjusted was easily adjustable.
I didn't really expect anything else, but laying in the hammock was very comfortable. Having a bad back, I was a bit worried that I wouldn't get proper support for it (This has been an issue with some spreader bar hammocks I've tried), but this didn't seem to be an issue. Reaching the zippers was sometimes a bit annoying, but I think this is mostly a matter of practice for me.
One thing I didn't expect though (As nobody had really mentioned it before), was how comfortable it was to just sit across the middle of it, fully on par with a very comfortable beach chair. I guess many of you who has tried a lot of different hammocks don't quite see the big surprise here, but keep in mind my background is exclusively spreader bar hammocks and my experience with them is very unlike what I just described if you try to do the same.
Packing the thing together was the point I knew it was the right purchase though. The thing just magically tucks together in itself without ever even touching the ground. The #1 thing I hate about tents is the process of packing them, so this was definitively the biggest plus for me.
I apologize for sounding like an advertisement btw.
