A normal 48"-50" UQ should fit your hammock fine, if you don't think it will you could always order a custom one built specifically for your hammock. Are you coming to the Oregon Hang the 4th, 5th, 6th? There's a thread in the Hangouts/Trip Planning category.
I will not make the Oregon hang, as I am in Texas until the 10th, but I hope to make the next one.
I just got done with 100 miles of paddling on 2 rivers in Texas, and my paddling buddies are not happy with me as they now want hammocks too!!
