After the big ballast upgrade I did a couple years ago - posted here , I decide to add ballast under the front seat & right seat (behind the driver seat).

The extra ballast in the front allows for a cleaner wakeboard wake. I used external ballast bag for a while (the Ronix 8.3, which is great, but I'm tired getting wet, especially in Winder) so I decided to add a new pump, and while I'm at this did a system with a Y valves to also fill a bag under the right seat/bench (for goofy surfers).
