I've attached a diagram of how we run our ballast. Sometimes it's just surfer/driver, where we would add an extra bag but normally it's surfer/driver/spotter. The 2x750#, 1x400# and 1x400# IBS are all subfloor/cushion ballast. The 4x250# are all sacks just laid on the seats in the cabin. It's not in my sig but we run a suck gate as well, vertical spine mounted directly above the "L" of LSV lettering. We are regular (not goofy) riders so adjust as required.
