I think I'd go with a 2 stage plan. Have most of the "normal" things to shoot with in location A. If things are going really well and these business connections seem to be using safe and polite gun handling skills then I'd bring out the more fun things. I'd probably store them somewhere else so I could choose myself to use them or not based on how it was going. Yes, that's already thinking too much about it. But I'm a "wade into the shallow end and see how it goes first" kind of guy.
