IMO opinion best is DoubleBull but pricey. For the money I like the Ameristep Backstrap. It is heavier material and I've been picking them up on sale at Gander Mountain after season last couple of years between $50-75. I've got several and will set up two at each of my bow locations so can hunt wind directions. They are large enough for comfort swivel chair, Caldwell field pod, cross bow and even one of my kids in a chair. We've often hunted 2 in them. However, it would be a little small for two full size adults tying to video with larger camera.
