Malibu 23 LSV wakeboard wake

Hey guys and gals,

I just sold my 97 Nautique SS that was basically a SAN. It had 2150 lbs of ballast and the wake was amazing.

I recently purchased a 2010 LSV and I am trying to make the wakeboard wake better.

It has the stock MLS system with two rear tanks, middle and front tank plus the power wedge.

Are there any recommendations on the IDEAL setup for wakeboarding without having ANY bags in the seats.

I can plumb my own ballast if necessary but it needs to all be hidden.

Also, I heard something about the wedge being great at "two clicks up" but it wont move while we are at wakeboard speeds. For surfing we can move it around and make a freaking huge wave but with wakeboarding it doesnt seem to move. Thanks for the help!
