With 750lbs back there plus the stock ballast yours will be even better than ours. I only have two fat bricks (350lbs) back in that corner. Just put some bodies on which ever side plus in the front to lengthen the wave and it'll be sick for sure. Or if you have tabs those do a great job as well. Have you posted up pics of your 25? I might put a 1000lbs sac on the port side to make it even bigger soon.
