In my 17 Pro I put 1600's in the lockers and I put a Fat Brick on the swim deck(surf side). I surf regular and I have tab at 80% and trim tab at 15%. The arms of the 16's are folded back to allow a little storage so I'm guessing I have about 4300lbs total. The wake is pretty decent but I'm a big guy so I want(need) more push. I was thinking about getting a 1500lb bag that would go on the back seat and wrap around on both sides. I'm leery about it though because I don't know if the seats take the weight?
