Yeah, the stock wake on the LSV is not very big especially if you don't have many people on board. It really depends on how big you want the wake. You can keep adding as much weight as you want and the wake size will just continue to grow.
Those some 750's in the trunks and put another 500 or so up front and the wake will be huge! With that much weight you really do not need to use the wedge.
You can also plumb in sacs on top of the locker tanks if you wish. PM me if you want details or check out www.themalibucrew.com
if you're not already on there.
