This is always an enjoyable topic, full of nooks & crannies, and a raftload of swings-and-roundabouts and 'orses-for-courses. So much depends on personal taste/habit/obsession, and on where and when we're touring, hence weather.
A few notes:
1) Ian, you might look at this item:
https://www.nemoequipment.com/product/dragonfly/ I just bought one from our local outdoors store, Bushtukah (a nice homage by its owners to 'Strayan, which I reckon not many of its customers recognize.) Be advised that NEMO's products are in high demand, and several models are listed as "out of stock".
2) My purchase is a bit of an act of faith that my arthritic hips will relent enough to let me use it next summer. I bought the Dragonfly 2 P tent (rather than the 1P) because it has about 5cms extra headroom than my otherwise excellent Tarptent Moment DW, and is generally roomier. The D'fly 2P is advertised as a 2-person tent, but when I erected it in the store, I saw that it would be suitable only for two very slender persons who like to be very close to each other: interior width is just 45", and that's at the wide end. I'm 20" across at the shoulders, so it's nice'n'roomy tent for me alone.
It weighs 50 oz all-in (all weights & measures US-mode). That's about 3 oz/85 gms more than my Tarptent
with the optional-but-extremely-useful end-to-end crossing pole; essentially, the same weight.
3) Julio, my Tarptent Moment has a
very sturdy floor, Julio. The maker does not recommend a groundsheet, unless you're using the tent in very rough conditions. I do use a groundsheet which I cut to size from an ultralight space blanket -- weight is maybe 30 gms.
4) As a habit acquired from long paddling practice, I almost always carry a small Nikasil tarp, approx 6' x 8' & 400 gms. (US, sometimes Canajan measurements).
5) Come spring, I plan to sell my Tarptent and (likely) my 2-person Hubba Hubba-mit-footprint. Both vgc condition, no scrapes or tears.
