I'm after a lightweight one man tent.
Choice between two, the MSR Hubba and the Mountain Hardwear Sprite 1.
The Hubba is free standing which is handy if 'pitching' under a pavilion, and is a little more spacious inside with a bigger vestibule, for a small weight penalty more.
The Sprite, has to be pitched with pegs and is smaller inside with next to no vestibule but the overall package is a tad lighter.
I've used and been very happy with my old MSR Ventana. MSR have replaced damaged poles overnight. The newer tents have better poles but I like their attitude with warranties.
I've no experience of Mountain Hardwear tents, though the reviews (mostly from the US) are universally positive
Short of a Harry Hill fight, which to go for?
I like the MSR Hubba and Mutha Hubba - well made, designed and seem stable and weather proof. BUT the ones I used were all mesh inside - bad in windy places or where you get lots of condensation / after a nights rain as you do get wetter than with a fabric inner.
I'm not sure a Hubba would pitch without pegs but, in any case, the decent vestibule wins it for me.
The Hubba also has the option of the "Gear Shed" which would make it more flexible when you don't have as far to carry it.
Mind you - I've yet to be convinced by al "all-mesh" tent design. I reckon it could just be too chilly for Scotland - although I can see the attraction in warmer climates.
I should have added, it would be mostly used for bike touring in the US.
I had condensation issues with my mesh innered MSR in Oregon near the coast with heavy morning fog. The flip side is that it didnt get too hot further inland.
EDIT

I'd use it without the fly, we did this several times on the TA camping under pavilions in city parks when there was the threat of overnight thunder storms.
No experience of MST tents (but several stoves!), however I've used Mountain Equipment tents in Chilean Patagonia and thought they were very good. The folks I was there with use them year round in all sorts of nasty weather and swear by them. If it's ease of use, sturdiness, and all round competence you could certainly do worse.
Met a guy on my trip who had the Hubba it was tiny. He was happy with it. I was happy with my Tadpole.
I've the Hubba Hubba.
Great little tent IMHO.
I've the all mesh version, but even then, with a decent dossbag it's spotty dog.
Packs down well, & is nice and light, and as Colin said, the vestibule is a decent size too..
