Bill,
I don't have a problem shooting out of the blind with a 66" longbow. There is enough room at the top to move the bow about 30 degrees from side to side. Now, having said that, you'd better be ready to shoot when somethings in that 30 degree window, or it's a no go.
I honestly don't know how much I'll hunt out of the thing. I bought it so that my daughter could sit in it with me. She asks me a lot if she can go hunting with me, and this is a way that she can stay warm, relatively dry, and still see a couple of deer.
