Our old rig had a Traveler and an older model Hopper and Joey. On our new rig we have a traveler and the Hopper 3 and Joey. Have had 211's and Wally's in the past, but IMHO if you have a Traveler go the full route. On reflection, an older Traveler may have to have some modification to work with the newest Hopper, but would work fine with the older (not 16 recordings at a time) type.
