Diesel or Hero
Definitely the Diesel is superior, in my opinion. Possibly the best single boat ever made. Don't get me wrong, there is nothing wrong with the Mamba. It is a good boat for sure. I think you'll find the Diesel is better in overall performance and enjoyment. My other SUV recommendation would be the Jackson Hero class. The Hero is the modern day "Y", in my opion. (The old Wave Sport Y is a classic great boat.) The Hero is a most excellent boat, ... as is the Diesel. They are two of, if not the most, greatest all-around boat designs ever created.
