I have a Double Bull T2 blind. It works great while hunting with a bow as the birds pay NO attention to the blind. You can easily draw undetected. The only problem with the T2 is that there are a couple of blind spots (no pun). While filming last weekend in Illinois, it's easy to see why the boys at Double Bull created the Matrix. It would be my pick for a new one.
Mobility is limited only by how far you want to carry the blind. Double Bull blinds are not very heavy (your back pack full of deer hunting stuff probably weighs the same or more) but in the spring my legs aren't used to carrying anything but my gut around!
Hopefully, Petey will get some video uploaded soon from the blind from our weekend in Illinois.
