I am definitely not a veteran at bringing games to shows but my willingness to take games is in direct proportion to how confident I feel that people at the show will help look out for my game(s). For Pincinnati I knew there would be so many great pinheads around, most of whom would be ready to kick someone directly out the door for being a dick to my games even if I wasn't there at the time, that I was willing to bring my games. I do think it helped to have the rules card on the games but if I didn't have a good level of confidence in the attendees not being assholes and / or more people than myself helping keep an eye out for everyone's games I'm not sure I'd bring anything more than a beater or two. At both Pincinnati and the Louisville shows I've taken games to the experience has been fine and rather rewarding.

It's only about 2 - 2.5 hours away to Cincinnati, bring em next year!
