Welcome to GT! I too look forward to all the stories you'll have after you bring your hound home (and start dressing him up! )
I have no experience with BCs, but I do know that most adoption agencies (certainly those with a kennel) will let you bring your dog(s) to meet prospective greys you're looking at, so you can see how they get along and let your dog help choose.
I used to have a horse when I was younger, and sometimes walking my grey makes me feel like I'm leading a very small thoroughbred alongside me on halter.
