X-Mid Pro 1

I could skinny pitch my 1p xmid pro anywhere you could fit a cowboy. Some people hate skinny pitch but I loved the versatility. 

Ive owned a mid 1 and now the aeon li. After two pitches it seems pretty straightforward. Easy to see where you go wrong/ adjust in sequential pitches. While its not AS easy as a xmid, its pretty easy

I tested both. Wound up selling the Aeon Li and Keeping the Xmid Pro 1. The main reasons were more interior space and better ventilation. With a single door on the Aeon it got pretty toasty inside, while the two doors allowed a breeze on the Xmid. Not really an issue unless you are using it during the day, I suppose. But sometimes I reach camp early and want to take a nap away from the mosquitoes. The Xmid does have a bigger footprint, which can be a mild headache when pitching. But it definitely has more room inside to sit up, fuss with gear, etc. I'm 6'1", so that extra room was appreciated. Also, I found the setup was quicker because there were no corner strut systems to fuss with. That said, both tents were great and light.

I used my x-mid 1 pro for shasta but the weather was good. The solid should be more, well, solid. I would expect that if the weather is good enough to want to climb it would be good enough to use it.

I've owned both. The Durston is slightly faster to pitch but both are very easy. Both are excellent in harsh weather. The aeon has more options for controlling ventilation and breathes somewhat better but both a pretty good. The aeon has a smaller total footprint and can be pitched without the vestibule to squeeze into terrible spots if you really need to. I would get the Durston if you prioritize livability and ease but get the aeon of you prioritize footprint and ventilation. You will be very happy with your decision regardless!
