Adding ballast to an I/O help please

I have an '99 Sea Ray 210 Bow Rider with a Bravo 3.

I would like to improve the wake by adding some ballast. Last year I bought a Fat Sac and placed it in the ski locker. It helped a lot but I think I need more weight up front. I added some old plastic sand filled weights under the front seats (maybe 150 lbs worth) but for next season I would like to go with a ballast bag instead.

I am trying to decide if I should add a pair of side sacs or the V-shaped bow sac up front. I like the idea of the V-shaped one because it will make the best use of the space under the seats. I also like the idea of just having to fill and empty the one bow sac instead of 2 side sacs.

But, the ability to move around the side sacs, even taking them out from under the bow seats if I had to, is appealing.

I am also considering adding one Fat Brick in the engine compartment, opposite the batteries, to help balance out the back. The Pro X Mastercraft X-2 Rear Sac would actually utilize the space better but the fittings look different and I am not sure if they will work with my Tsuanmi pump.

If anyone has any recommendations on the best way to weight down my boat I would appreciate it. Also, if someone can tell me about the fittings on the Mastercraft sac I would be much obliged! Is there any way to plumb the bow sac and ski locker sac together?? Then I could just fill one sac and let them both drain into the bilge.

Thanks

Oh, and I have already downsized my prop so hopefully I am good there. I only went one size, I may need to go two by the time I am done!
