I buy and sell a lot of gear on the swap…just so I can try things out.
In what you are looking at, I've had an oware 10×10, two supermids, a luna 4, and an ultamid 2 with perimeter netting.
1. Oware 10×10 – I thought that this was a fine shelter…pitched decently, though larger than what I needed. Yes, it doesn't come with a vent….and, unlike the supermid, and similar to the luna 4, there is a vertical seem mid panel, whereas the supermid has a horizontal seam near the top. How much this really affects things? I don't know..but supermid is easier to seam seal (I use the tarptent method).
The big thing that concerned me with the oware….was the stitching. It was nice and straight (good craftsmanship), but it was only single stitched……luna 4/supermid at least double (or maybe triple in some spots? I would have to look).
If I remember, it was 30oz or so, so over spec, though oware lists the same weight for the 9×9 (28oz) as the 10×10 (28ox) so not sure what is up there.
2. Luna 4 – Not enough catenary cut, workmanship a bit off. (I've talked about BPWD on the swap before). I wouldn't consider them…you'll save money but always think "something else is nicer".
3. Supermid – My personal favorite. You said the weight was off for being smaller than the others, but the opposite is true in my experience. So, one supermid was 8'11" (so only 1" less than oware 9×9…though I haven't had an oware 9×9 so didn't measure directly), the other was 8'9", though 2" taller than the other, so there is some variance in specs. (well, one was an older designed supermid….maybe they did change). The big thing: both underweight by quite a bit. MLD lists it at 29oz…but one was 25.2 oz (the older one, seamed sealed tarptent method), the other 26 oz. Not sure what is going on there, whether its just outdated info, or trying to push cuben supermid sales, or ?
Anyway…tight pitching shelter. There is a catenary cut, so there is a very small learning curve with pitching…but generally if you pitch the 4 corners really tight then put up the pole, the catenary curve will be stronger, so less space near the ground. If you have a bit of slack in the 4 corners then pitch it, there will be more space off the ground and also less of a curve. You'll get the hang of it in 2-3 pitches, but that is the only learning part…whether you want it low/tight to the ground or higher off. A square mid is the easiest type of shelter to pitch.
As for an inner net….I currently have a bear paw pyranet 4…I'm 5'10" and there is lots of foot/head space. You are taller, but with a innernet, you can always squish up your feet end against the pyramid net since you don't need headroom there, and I think you'll be fine near the head.
4. Ultamid 2: I am of the opinion that I don't like perimeter nets which this one had. In a slight wind it becomes kind of a pain to get all the netting "inside". And they are still kind of heavy for what they are (I think the netting on the ultamid 2 added like 7-8 oz, without a netting door…
