I hope you realize that you really shouldn't keep the windows wide open at all except for where you plan on shooting out of with a bow because you don't want to silhouette yourself for the birds to catch your movement which they will do if you have a window open behind you or to your side. I watched another hunter a few years ago from 500 yards away one day do exactly that. Every time he moved I could see his movements because he had the windows wide open. Imagine a turkey that has much better eyesight than a human how well they can pick up movement even in a blind because a hunter has himself silhouetted.
For turkeys the 3D means nothing either for camouflage and concealment. That blind can be solid Blaze Orange and it won't bother them one bit as long as you don't make any noise or don't get caught making any movement that will draw their attention.
And I've found that an old Army duffel bag is the perfect carry bag for a hub style blind. It give you extra room to carry decoys, chair and other items inside the bag with the blind.
