Stable Sativa strains?

I am interested in what sativa strains can be considered seed-stable or an Inbred Line ? I know these are:

Durban Poison
Haze

What other genetics should I look at for stable sativa strains?

Try an orange bud. Also look up Medusa. It is a hybird. mostly India, but I think you will like it. Good luck, and happying growing.
