Ultra light tents

Hi All,
I am looking to buy an ultra light tent. I am a 55 year old female, 5'1" and 46 kg and fairly fit. My pack fully loaded with a weeks worth of deyhradted food and water is about 15kgs, which I cope with very well. So I am looking for a tent that will do at least to the snow line at no more than 1.5 kgs. So far I have considered the MSR Hubba and the Exped Vela 1Ul. Does anyone else have any other ideas of good tents to have a look at that will fit the bill.. I would prefer to have 2 layers but will go single skin if I have to.
