Hope this response isn't to late for your needs.

I have the Double Bull T2. For a single hunter its a great blind, as someone else stated there is virtually now wind flap, and it's easy to set up. The only problem that I had with it, that should be easily fixed is that while gun hunting in it we had a steady moderate to heavy rain with temps between 38-42. I noticed that there was a fine mist coming from the fabric after awhile. I'll try some water proofer on it after the muzzleloading and late archery season are over with to see if that will help.

Last season I had a real nice buck 8-10 pt following a doe, they came within 5 yards of my blind, but they came up from behind me where I couldn't easily turn around and shoot, due to all my gear, chair, and portable heater. I was shocked when I saw how close they were.
