I am truly amazed at what these dogs can do, how precise they can follow instructions. However, still not my type of dog. I know many of them, and they're bred so high strung, they grate on my nerves. Some are calm enough around the house, but I'm told many have to be locked away as they're just too wired. Also, I've seen a few cases of redirection (with Rotties too), where the handler/owner actually got bitten.
