After all summer messing with our ballast in our 2014 RZR, I think we have, at least the port side, dialed! Put the W005 sack in to replace stock "surf ballast". I think it's about 900lbs. Around 1100 with hard tank. If we have couple extra people it's perfect, but just the wife, my kiddo, and I we add two fly high fat bricks. I think they are around 150lbs. Each. We put those on the seats. Bow tanks both full. For a beefy powerful wave, I set taps at 4 and speed at 10.6. For a longer pocket, taps at 3 and speed at around 10.9 or 11. The size of the wave shrinks a bit with the longer pocket. Thanks everyone on here for the help! Sad day getting the boat ready for winter.
