Wakesurfing in a X-30

[madmuffin]

Getting ready for wakesurf season here in the Pacific Northwest. Have a 2007 X-30 and wondering if anyone out there has mastered ballast for wakesurfing. I had a 750 flyhigh in the rear port compartment last season but ready to add more. Bought another 750 that I may use on the port side seat or floor? Have the three built-in ballast tanks also (fill them all?). Anything else needed or any suggestions on setup? Thank you -
