Got it!!
Blacks Manchester, got it for £152 as the xt I wanted to see was ripped & therefore not for sale.
Only had it up in the garden but it seems a great little tent:
First Impressions.
It's a well-made bit of kit and 'looks right'
2 pole design. Poles are pre-bent but have a small angled section at the apex of each arch which seems to make them extra springy - erecting the tent requires a 'longbow pose' but hopefully this will pay dividends strength-wise. Materials are certainly lightweight but it has a quality feel. Fly seams not taped and sealant is available 'on request' rather than supplied 
Easy to put up (I left the instructions in the shop after the demo / trial run) so it must be simple
- will contact Lightwave for the PDF. Inner first and then fly velcros & tabs onto poles ends - just like the WW
Will have to experiment with the guying and tab positions to get it just right but first go was pretty much spot on. One concern would be the 6' run between the poles where there's nothing to separate fly and inner fto stop them touching - hopefully guying will sort this.
There's a weird 3rd short pole that keeps the front vent open but it appears to put strain on the top seam, worried this will evolve into a weak spot so I'm going to look at just guying the vent open instead.
Comes with the sexiest pegs you've ever seen - red square jobs, too nice to use - they'll 'walk' but only 8 (tent needs 11-15), 4 nylon loops which seem superflous and no pole or peg bags 
It's certainly roomy enough for 1; 2 would be silly, unless it was one on top of the other....
. The porch can only open 1 way but there's enough room for boots, cookstuff etc. Seems fine for cooking.
Packing poles in a roll-mat & pegs elsewhere than the side mesh pocket will allow this to be compression sacked into a very small bundle.
Certainly so far it seems a good bit of kit and reasonable value.
Thanks for the pointer - it was a good one
