I'll be upgrading the rear lockers to 750's. Or should I go bigger or is this the biggest it will hold? And what about the center? Is it sufficient or does it need to be upgraded and what size is it currently? I heard the ballast pumps are slow, not too big of a deal but what's a good affordable pump upgrade? And does the rear lockers need to have the extended Jose called a ballast buster...? I think that's what's it called on wake makers. What prop as well? Thanks for the help....I know I just asked like 1274727 questions.
