Have you used the Hornet Elite? I have been looking and the size is right but is it backcountry worthy?Nemo Hornet Elite and the MSR Hubba Hubba are tops on my list. The zpack duplex also interests me.
If you're not looking for ultra lightweight, don't discount Kelty. My first backpacking tent was a Kelty Grand Mesa 2. I've used it on countless multi-day trips in CO and it's done well for me. Including footprint and stakes, I think it comes in a little under 5lbs. Cost was about $100 too.
My only complaint is that there is only one door and vestibule. Not a big issue when you're by yourself but a bit more of a pain if you have another person.
