I have this same boat. Wake is great. In my preference, a good set up is:
- 550lb in each rear locker (took out the stock tanks)
- Stock center
- about 650 in the front
- 250 under the port seat
- 250 on the floor
With this setup, sometimes a full 650 in the front is a bit much and the wake loses some of its peak. May or may not matter to you. If it is very extreme (like empty fuel tank and only a driver) the proportioning is so nose heavy that the boat seriously won't turn. Kinda scary. Since we usually only ride with 2 people in the boat, I could probably use a few hundred more towards the back (planning to get bigger sacks soon). The wake's not huge, but it's good. I could probably stash another 1000lb of lead throughout all the hiding places and it would really be macking.
You can read about weighting all day long. Bottom line, just experiment. Everyone has different preferences and opinions. I can't tell you how many times we've found the "perfect" setup only to change it when we found the next "perfect" setup. You could always just go for broke and add weight till the thing barely gets up anymore. Then you just play with proportioning to adjust the shape.
