I would say keep your board and get the double agent anyway in about a 152. Its convertible to twintip/mutant so you can adjust it depending on the day you are riding. Sometimes its nice having a small directional/mutant for waves or choppy water, but you'll probably find yourself using it in twintip mode most of the time anyway.
