Try a search, this subject has been discussed at length many, many times. Also try Planetnautique.com. There are a ton of really detailed ballast installs there.
Anyway, to answer your question. If you want to really mack it out you're gonna want 2,500-3,000#s. I run 550-600 #s in each rear v-drive compartment, a custom sac in the locker probably about 7-800 #s and an open bow triangle in the bow probably another 7-800 #s. Plus 300 #s in lead to move around.
I have 2 friends that run the integrated bow sac. It is nice because they have use of their bow where as I don't, but it's not enough weight alone. You can get away with it if you use an extra couple hundred pounds of lead up front, which is what they do. I'd guess the integrated sac probably holds 3-400 #s when full.
oh, and of course a wake pic. 24-25 mph at 85', rider is 6'1"
