I have the solo tent, with cuben floor and the door (beak wasn't available at the time). The accessories were bought after the tent. I like it quite a bit.
I find the tent actually quite resilient. The netting floor has worked as described by Joe on his site. I'm actually quite impressed. I burnt a couple of holes in the net (floor and door) with a "cigarette"-like ember. Joe charged me a very nominal fee ($15-20). Looks as good as new. Great service.
The cuben floor with attachment hoops, was the best addition. I didn't bother having it sewn in and just keep it attached when packing the tent. Packs very very small when you fold and roll. Up to you whether you want the floor sewn in or not. Save a bit of weight (couple ounces) or have an extra layer of material between ground, or option to use floor without tent (?).
I was considering getting the beak when it came out and retrofitting it. Joe told me not to bother and am kind of happy with the door. You can raise or lower it from inside the tent. It's behind the main pole so doesn't take away from floor space. You can keep it tight to the bottom with rocks etc to get better coverage against wind/rain. You can lower the top half of door for better ventilation and keep bottom up to protect when lying down in tent.
I haven't used the beak so have no idea the advantages. I suppose it would be neater/tidy inside and you can use beak for shoes etc.
Joe is a stand up guy and very helpful with questions. Good luck.
The only downside of the hexamid is that it takes up a bit of real estate with the guylines.
The other tent I have is the Tarptent Double Rainbow. That one is a total no-brainer at $260 all in. Great for two people, easy set-up, small footprint. but it is a pound heavier.
