Have a look at my reviews of the Big Agnes Seedhouse SL1, Fly Creek UL1 and the Vaude Power Lizard UL. The two Big Agnes tents are definitely 1 person only tents so you'd need to SL2 and UL2 respectively but they are excellent tents and you'll see why I think so from my review - www.journeymantraveller.com is my blog.
The Power Lizard is a contender too. It is a palatial one-person tent and a snug two person tent and it is only 1040g (2.3lb). It can withstand, according to Vaude, very strong wind and, having used it, I can certainly see that may well be the case. I did not like it, but that wasn't because it was not a good tent, I just preferred the layout of the Big Agnes tents. If you are solo camping much of the time but need a two person tent every so often, it is worth a look.
