Someone can correct me if I'm wrong but I don't think any Moomba/Supra have hard tanks? It's all bags is it not?

The MurderMax thread can get you started with plumbing/adding additional bags under port/starboard seats. I get the sense that's what most people are doing first when they want more ballast. After that, I think you go with #500 of lead to ensure your ballast amplitude is as close to 100% as possible, (someone correct me if this is wrong). By doing those two things, I think you get pretty close to your max allowed extra weight (e.g. #2500 for Mojo).

So you'd be at #4000 standard ballast + 1000-1500 additional depending on how big of bags you put under the seats + #450 (73 gallons of fuel) + #500 lead = #2000-2500. (Still need to account for people on board as well.)
