I live 25 miles from Bob's shop, and I've shot just about everything they ever built at one time or another, with the exception of the newest models....all very nice bows, and shoot as good, if not better than anything out there....great grips too.
The only Bob Lee I have left is an 80's model Thunderbolt 1pc recurve. If I remember correctly, Rob said the Thunderbolt was discontinued in the early 90's. It's definitely the most graceful and sexy recurve ever built, and possibly the quietest recurve I've ever owned.
I'd try to shoot one if possible, but I'm thinking you'll be happy with whatever you decide on.
