Tarptent Stratospire Li or Double Rainbow Li for a really tall person

[TJE0705]

Im looking at both of these for an upcoming backpack elk hunt and was wondering which would be best for a very tall person. Im 6’6” and around 205lbs. Out of the 2 I like the design of the Stratospire more but looking at the specs the Double rainbow seems larger. I will be using this as a tent just for myself. Thanks for the info guys.
