Are you planning to be in front of or behind the rider? We have found its a lot easier in front of the rider because the rider does not have to worry about the rope for the tube (which can be a bit intimidating at first) or all the spray from the rider. For either, it's best to have to go pro on a 3-6ft pole. The shots can be awesome though. We have a "super mable" tube and it works fine. The 3 person more stable tubes are good too.
