When I was at the factory last fall, the factory people said it actually depends on the boat. They said the smaller boats (ie X2) should be just like 92Maristar says: put the opposite side down to provide a bit of lift to that side to dig the side you are surfing in further. However, apparently the bigger boats it is opposite.
I just got my X2 with attitude adjustment plate, surf tabs, and plug and play ballast delivered yesterday, so I'm gonna start playing with them to optimize things. If you--or anyone-- figure stuff out, please share.
