I like International Batman personally, because it not only connects him with the wider dc universe but also gives the bat-family time to shine. It shows he trusts them to handle business while he handles personal matters.
Not counting Catwoman, Ghostmaker, Harley, Clownhunter, or Jace Fox; Bruce can rely on the two Batgirls Steph and Cassandra, Tim, Jason, Barbara, Helena, Duke, Luke and his cousin Kate if things go wrong and Dick is only a call away if needed. I say let him go on out of town adventures with all of them available to help.
