Has anyone swapped out the stock locker bags for the 800lb Sumo sacks? I have these already that we used in our old boat. They are 24x24x50, whereas the Fly Highs are 20x20x50. Don't mind getting the Fly Highs if I need to, but it all adds up quickly! I think these will fit, but since they have the "waterbed" type fittings, how much modification will it require? My gut tells me to spend the $$ and go with the Fly High Pro X so it's a 5 minute swap, but wanted to get input from the experts.
