New Boat ..07 moomba lsv

Hey guys, just got a new boat this year.. A 07 Moomba lsv. I know its not the best wakeboarding boat compared to the newer boats that are out there but its what i have to work with. Just trying to make the biggest wake possible. Have gotten pretty good over the summer landing tantrums and 360s. But was wondering on what els i could do to make a bigger wake. it puts out only about 1200lb ballast. it has a wake plate but with messing around with it i have seen it doest do much. just trying to get as much height as possible so im thinking adding a fat sac is probably the only way? Also what do you guys think about the moomba cruise control? i have found it really hard to use and maintain and equal same constant wake.
