Hi I'm new to the moomba world of boats. I just sold an 82 mastercraft stars and stripes to switch over. Needless to say there was no set up needed to ski behind. the moomba is a little different. Most of the time its just me and my wife. If anyone out there can give me the principles behind the ballast weighting so I can apply it to different situations that would be perfect. Otherwise what set up do you find gives the best wake for skiing. I have the stock gravity III system. thanks
