Brian wants to know what's a good choice for cable management, while traveling. Leo says that there are plenty of choices out there, but Leo tends to buy cables from Nomad, because they have cable straps attached.
There's a great system called the Cocoon Grid It, which has a bunch of rubber straps in a gridded array that he could use to keep his cables secure and tangle free. There's also the ThinkTank Cable Management Bag and Case Pouch.
It's also a good idea to wrap his cables using the over/under technique perfected by audio engineers. He should look on YouTube for how to do it.
