The Litmus is a good board for everyone. When it was first released as the DLX in 03, it only had the cupped outer fins, as was somewhat loose when ridden on center. In 04, the DLX was dropped, and the Litmus was introduced with the same shape and cupped outer fins with the center fins added for better control for beginner riders. It's really got good grip up on edge, and excellent pop. In other words, the beginner will probably want to ride it with the center fins bolted on, but try it without, too- it rides really well with just the outer fins.
