This is a pic of the wave on my 2006 LSV with just a 750 in the rear locker and 400 in the front, no IBS, 2 kids and wife on board. If your wave looks something like that, then you just need to practice. Give it a little time. You say you are a first time surfer and weigh 210 lbs so I think it's a little unrealistic to expect that you will be able to freeride right away. You have to get a feel for it. Also, it would help if you got a little bigger and floatier (surf style instead of skim style) board.
