boy that Big Agnes Fly Creek UL1 is something, packaged weight at just over 2 lbs and as your photo shows it, you would even have ample room to have a couple of panniers in there without issue, even more so for a skinnier fellow like me. Its even on sale now at rei for 240 american.
pretty amazing the neat tent designs out there now.
Last year got a 2 per. Hubba hubba and its a couple of pounds lighter than my old tent, but these 1 per ones are really neat and compact.
It also packs down to a tiny little package. I was very pleased with it on my tour through Appalachia.
