I now pack an Aeon Li for good service with lightest weight for week and longer trips moving daily in NM & CO Rockies, 3 season: light; fast taut setup; good in wind; good enough for rain, with condensation being biggest issue.
However, for the sustained gusting wind & rain I’ve experienced in Scotland (albeit short durations, weekends from work there), I’d worry about shallow bathtub floor (already mentioned) and quite small interior and vestibule volumes including condensation, with Aeon Li.
(Aeon strut lengths are barely tolerable for me horizontally very near top of Durston pack.)
I don’t have a Notch Li, but it sounds more suitable for Scotland, albeit with weight added. Suggest https://sectionhiker.com/backpacking-across-scotland-gear-list-may-2024/
I also have a Durston Xmid2 Pro and love/prefer its much larger interior and vestibule volumes when I’m not relocating daily, thus caring less about small weight penalty and slower storm setup time. It can be well rigged for CO & NM thunderstorm wind and rain using long pegs and apex guylines, but it is a slower, more fiddly set up. It is much better about condensation than Aeon Li, in my experience, since volume is larger and walls are not so close.
For me with Xmid Pro2, a 4 peg set is quick; but a really taut, uniform 4 peg set is usually longer, fiddling with stakes and pole heights, especially when ground is not truly flat & level. Apex rigging for storms is then straightforward but adds another time step.
The Mid1, if you can find one, removes the weight penalty vs. Aeon. Based on my XMid2 experience, I think XMid1 provides more useful interior and vestibule volumes but will requires more time and care for severely windy & rainy setup vs. Aeon.
(I used a 2017 Zpacks Hexamid on the AT and a 2019 Duplex on the CT. I still own these and use/loan them occasionally; but I cannot recommend for Scotland. — And I’ve used many more now out-of-production tents before these. With tents and tarps, it’s always tradeoffs, even while technology has been improving remarkably.)
