Hi, Same as you, I came from I/O's and only went on one wake boat on vacation last year. We bought a 1 hour surf lesson on vacation last year and within a month I had sold my stern drive and ordered a 2018 Mojo. We love it and have no regrets. They drive great under power, docking is different but not hard. I do have Autowake and like it. It works well and I would purchase it again. As for which model Moomba, that's personal preference based on looks, layout and what works best for you. They will both surf great with upgraded ballast. One option I would recommend is the G-6 ballast system, especially if you have Autowake.
