Regarding the 5600$ difference, 3500$ is the pro tower which you can get with the Mojo so really difference is only about 2K$ between the two. Now, are they both built with the 3.0 surf tabs? I personally like to Mojo for better portability if you tow, otherwise, if you own a lake home then the Makai would offer more room. Otherwise equally equipped you're paying 2K$ for an extra foot of space, they even look similar in design. Question is whether the extra weight in the Makai benefits from the larger 450 engine for comparable performance. The Mojo has been fine with the 400 on previous models. That may be a significant differentiator if you have to spend the extra 7600$ to achieve similar performance. Maybe someone here with a Makai can chimed in on that issue.
