If it is very rough I slow down to 20 and it is no problem. The craz would be better in rough conditions. If money and storage is not a problem I would go with the craz or mojo. I learned to surf behind my friends 05 Avalanche. I love the wave my mondo makes (with the right ballast). It has more push than me friends boat. The reason I went with the mondo is I got a great deal at the end of the season and I wanted to be able to store it in my garage. You will not be disappointed with any Moomba!
