The benefit I think that comes from all of these systems is you could essentially run as much weight as possible and even weight in both sides of the boat and still have a good (or better) surf wave then trying to make the boat list using weight. I run 1100 left locker and 0 right locker...now I could run 1100 in each (or just my current 550 in right), adding more total weight to my boat, which should make the wake bigger. I would be willing to bet you could run your normal wakeboard ballast setup and then use the Flow system for surfing and not have to change any ballast. I think that's the biggest benefit, is not switching ballast between the two sports, which is a HUGE plus in my book. There are so many times we want to switch back and forth since I wakeboard a lot more than my family or friends, but it's so time consuming emptying the 1100 down to around 500 and filling up the 500 that a lot of times I just say "screw it, I'll wakeboard tomorrow" since everybody else just wants to surf.
