is your 370 center sac the factory KGB? if it's not, and you can move it i would put that as far forward as possible. try and get a 50/50 to 60/40 rear to front ratio. i forgot to mention that i have 2 60 lb tubs of lead that i move to where ever's needed to balance the boat out.
i plan on up grading to all of pro x series sacs next season. 750 on each side of the engine a 750 behind the driver, 370 center ski locker, the integrated bow sac and the big 1200 lb open bow sac. probably also get two 250 side sacs...they are nice and easy to move around to anywhere needed.
