Loaded up the hard tanks and extra fat sacs in my buddies Axis A22. Talk about a beast of a wake! All the stock tanks plus dual 750's in the rear and the wedge down. Beast of a wake. Definitely not something to run all the time though.
Looks like you need the under the bow pnp bag. My 12 will plane with 750s in the rear, wedge down, pnp bow under the seats and stock full. I also add another 1k to the bow. Bow weight will improve the wake tremendously, until you submarine of course.
