Tentsile tent

Hi!
I am thinking about buying a tentsile tent. It looks really really cool! I have on question tho. I am going to try to set up the tent between trees but further up than you normally would. How would I secure myself, incase the tent would fail? A rope between two trees, and attach to that? Thanks for any replys!

Regards Bjørnar.

If you can't get a a good anchor limb overhead creating a high line and hanging your rope off that works well.
