I watched it, and didn't get the "shock and awe" factor from it, really. It's not much different than what we had done to herd cattle from the main front corral into the holding/working alley. Open up a gate, use the flight-zone, push-them-to-find-a-hole method and in they go. I can see how it's idiot-proof because you don't get the chance of a gate getting slammed back in your face if an animal kicks it back at you. But isn't that what the ratchet system on those crowding tubs is for in the first place, as a bit of a safety feature to prevent a gate getting swung back at you at 90 miles an hour?
I mean it's a plenty good system if you've got animals that do have a flight zone but aren't crazy enough to want to take you out (I'm not seeing how that system is safer than one with a crowd tub), but it's not going to work if there's animals that'll just stand there and do nothing no matter how crazy a windmill you try to make with your arms! A crowd tub, IMO is best for something like this. Or a medina system, but backhoe, I think you'll have to PM me a diagram of your system because I'm not good with picturing how your system goes with just words.
So really it's nothing special. Just a rectangle with an exit point at one of the corners to shoo cattle into.
