JT, I've got an '06 Ebbtide 2000, pretty sure its the same hull as yours. I just got a pair of 350# sacks at the end of this season. We put one in the bow, one in the locker. It really helped shape the wake nicely. I may experiment with some more weight in the rear next year to get it a little bigger. But for some reason on that boat, even though everybody always recommends it, trimming up does not seem to help.
I can't find any decent pics of the wake right now, I've only been out twice since I added the weight and my wife likes to zoom in too much. If I go out again, I'll make sure to post up before and after pics.
