weighting my boat

[wakeboarder]

I have a Stingray 98' and i need to know how to place the weight so i get the best wake. the boat can only hold 1070LBS and it only has a 4-cylinder 3.0 liter. i courently have a 300lbs fat sac under the back seat. i was thinking about puting another 300lbs one in the ski compartment. and then 2 100lbs under the front seat. i would only fill all these up according to how much i need. what do you guys think? heres a diagram of my boat.

that will probably help some. you need to try it out then you may have to move the weight around to improve the lip on the wake.
