Own 2008 Moomba LSV with GIII Ballast (400lbs, 2 rear, 1 center) with Wake Plate.

Looking for suggestions on proper configuration for wakesurfing.

Considering adding an additional ballast (400lbs or so) that would sit on top of the seat directly behind the drivers seat. Wake is good when we have 5+ in boat but usually ride with 4. Wave could be better. Looking for some curl.

Suggestions?
