Let's start ballast set ups here since it has to do with wakesurfing tips..

Added a 580 fly high sac under port side seat (400-450 I guess it holds without pushing the seat up)
250 factory center tank
Added a 650 fly high bow sac under seats (will fill full)
Plate just down a hair to clean spray
11.8 to 12 mph
Rope is all the way out to show length of wave with actual push there.
