Seth, I take it you mean if you are only running the factory setup in the 01' you won't need front weight, right??
I do completely agree with tearing out the tanks and putting big bags in there. You reclaim storage for trailering.......not to mention the giant frickin booter of a wake that appears. We put the Pro-X 750's on either side of the engine. They probably only get to 5-600, but they fill up the space. You will have much better options for the ski locker, ours has a factory tank. You can fit 500 or 600 in there I think.
I can't remember our distribution off hand in our 02', but we put a couple bags in the bow as well and have about 1000 in the rear lockers, factory tank in belly (200-300??) and run another 500+ in the bow.
