Not sure about the cobra, but I just got a new viper x4. It's a real impressive stand. I couldn't be more happier with it. I struggled weather to get the cobra or not. I just wasn't sure about the moveable bar. This will be my first bow season, so I went with the viper just to have a little more secure feeling with the stationary bar. I'm sure you'll be happy with it if you chose to get it.
