I have a 16 mondo surf i am surfing it with wakemakers bagbuster 910 rear bags an extra 100lbs of lead up front and 400 lbs of lead in back that I move from side to side depending on surf side. As far as center platei like mine around 50-60% port tab @ 50% stbd tab @ 60% as base but I like mine @55% port and 60% stbd. We never have a big crew. Most days its just me and my wife and 2 small kids. If you can get a bunch of folks out with you with those same settings, you can move some lead to the bow and really get the wave longer. Our surf speed is 11.5 and it has helped our wave out with length.
