I ride my Gator Boards Harris at the parks all the time. It feels like to me, that the molded in fins help you get around the corners better and make it feel more stable for me. Its pretty easy to break free for a slider too. Check out the 137cm.
JStar Lyman, HL Motive, HL Era, LF Trip, LF Subjekt, LF Substance, HL Roam...... Subjekt & Substance are more all around boards for cable and boat, both are very aggressive off a wake.
