To answer the questions. I’m not sure what elevation Cincinnati is, but it’s not way above sea level. I have the 400 motor and I would say primarily our activity is surfing. I do pull the kids on a wakeboard but do not run any ballast - they’re still young and don’t need a huge wave to ramp. I’m early 40’s and have no desire to catch huge air on a wakeboard whatsoever but I do LOVE to surf.
