We used neon zip ties in the extra lock hasps, and on the way to RSA they never opened our cases. They were opened in Atlanta after we picked them up in the gun room & were rechecking our bags. We just dropped them with the TSA agent and ran because we had a flight to catch.
The neon zip ties are the way to go with zip tying your gear (case lock hasps & bow strings & cables). TSA will have black zip ties, but they don't have neon ones, so you'll know if they've messed with your stuff without having to closely inspect.
