Trace,
We have no problems getting a nice wake out of our 2000 Launch. 450lbs under seat stock hard tank, 400lbs in rear ski locker, 350lbs front custom hard tank, 300lbs lead in the nose, if we have more then say 5 people in the boat we leave it at that, if not I put one launch seat at 600lbs beside the engine cover.
Some people don't think this is safe or is a stupid idea but someone hanging on the side of the rack and leaning over really cleans up the entire face of the wave, BIG difference.
We ride at 9.5 to 10 if that helps.
