jrod, my last boat the little centurion took 2400.....plus people, with very little boat to sink.
Looked kinda like this....
Granted, thats the whole boat......I dont think any boat could take much more than a g up in the nose, but i bet the x2 could take 2g in the back, 600 in the nose, and another g plus in the middle.
The best x2 wake Ive ridden used the stock ballast with the bigger upgraded fly high sacks, 400 lead in the nose, a 600 pound sac in the walkway to the open bow, and another 600 pound sac laying in front of the rear seat.
