'99 Pro-Air and ballast?

My friend owns a Pro-Air with stock ballast. Has anyone removed the hardtanks and plumbed in bags in the rear storage locker? How is the wake with more weight?

I ride behind one from time to time but haven't sac'd it out (yet). It does get much better with more ppl, so it should be sweet with some real weight in it.

Removing the tanks involves removing the gas tank in the PAN. Kind of a PITA. I think most just opt to run additional sacs. I'm trying to talk the owner into running a sac in the rear locker and one the floor/ski locker (to start ).
