After watching a lot of dog work today and running the blind this afternoon, I think it's an excellent blind. Every part requires being on your toes, and as I told Sammie, "Don't take one bit of it for granted!" From the first angle entry to the last second of the exit from the fourth piece of water - it's a challenge. It was definitely a rush to run!
BTW, the out of sight part is not causing any problems that you don't have plenty of time to remedy if your dog felt like running a WB today.
