Ballast settings for surfing/wakeboarding?

[keatonwakeboarder]

I just purchased a 2010 X2 with 15 hours completely loaded for $55,000!
I need to know what ballast/surftab/where people should sit settings I need.
Some stuff to consider for settings, I have:
The B.I.G. system
Factory Ballast
Surf Tabs
and usually 5 or 6 people with me(100-180lbs)
