Picking up a 2009 centurion Falcon V Air Warrior. I am already looking to add some ballasts to it for wakeboarding and surfing. I like the idea of the wake shapers. The reviews and videos have impressed me along with just having to weight the boat equally. With that being said I think I would be happy with 2 1100lb sacs in the rear lockers. My main question is what is the easiest way to fill those without having to throw pumps overboard and hoses going everywhere. Can you intergrate the factory ballasts with the sacs im looking to add? For example, turn on to fill port side factory ballast and it fill my port side bag as well?
