Centurion C4 ballast set up

Hey my buddy just recently boat a 2006 C4 avalanche with the storm 1 series set up. (250 I think in the middle for ballast) we are wondering how difficult and what to run in the lockers and the bow. We have been looking at wakemakers an were are Goin to do the intergraded bow sack, but for the lockers we could put the fly high 750s on each side or we could go a little smaller with like 500 on each side. Need some help from centurion guys on how to make this wake nice.

We surf some but mostly wakeboard.

Thanks for the help
Jacob
