I'd much rather be in an open stand than one enclosed with a frame of bars. For gun season they are great, just not enough room to shoot a bow. Takes a lot of movement to stand up, draw and then lift your bow over the rail.
Fish, relax, I was just having some fun at your expense while making the point why I choose the Predator IV sight. Goose and Fish, help me out here, 7 pins? Discounting my position on this subject, how many pins are needed? What's your bow set up? The faster your bow, the fewer pins you'll need for hunting. If you are shooting an X Force at 330 fps, you can get ride of about 5 OR 6 of those pins. Even on a 3D range I couldn't imagine using 7 pins. I wouldn't hand out too many brownie points for the free sight but it will get you started. Good luck.
