Ive been look at the double bull as well... I had the opportunity to look at one at cabelas the other weekend and WOW it was super quite!, very roomy!, and super easy to set up!. The dude at the counter came over when i was sitting there tearing it down and setting it back up again...lol Not sure i would get a blind with Velcro. Seems like that would be loud in the woods. This Double Bull has zippers and some kinda pully system. I am by far no blind expert but i don't see how this blind could be beat. however, i am always open to suggestions.
