I test drove the mojo the other day and was confused when we went to surf the sales guy told us that he runs the stock ballast 100% on the surf side, empty on the non surf side and about 50% in the center tank. The wave was alright but really short it seemed like. Also we tried to ride it weighted evenly but the top of the wave would not clean up. Just wanted to know how every one else is weighting their boats for surfing.
