I think all 3 original bags are 400's so swapping won't help.

If you surf regular it is very easy to fill all your ballast and then move all your crew to the surf side (more seating anyway). You need a little list even with the suckg8. Obviously, deploy the suckg8 on the opposite side of the boat as the wave you are trying to surf. If you have a wakeplate start with it all the way up and adjust down until the wave is tall but still has push. Boat speed will be a bit slower with less ballast. Around 9.5-10 mph and adjust. You want the face of the wave dark, not frothy. Post pics or video if you need help.

Another thing to try is putting both rear bags on the same side and then adjusting crew to balance a little bit but keeping some list to the surf side.
