The JS Industries Black Baron 2.1 is a performance-oriented twin fin designed for a wider range of conditions than its predecessor. It features a narrower nose and tail for increased responsiveness while maintaining low entry rockers for excellent paddle power. The board has a deepened single concave through the center, with mellower concaves in the nose and tail to maintain speed. A key update is the addition of a center fin box, allowing it to be ridden as a 2+1 setup, though it's primarily designed for twin trailer configurations. The Black Baron 2.1 excels in waves from 2 feet up to overhead, functioning as a "speed machine." It's available in carbon fiber construction, offering a lively and responsive feel. This board is recommended for intermediate to advanced surfers looking for a fast, versatile board that can handle diverse wave conditions and provide a high-performance feel. Pros include its speed, versatility, and responsiveness. Potential cons might be its suitability for beginners in larger waves due to its performance focus.
