The Step Up is a model I use when it's over 4-5 feet and use particularly no reef breaks. Best ordered at 3-3 inches longer than your short board and keeping the same width but going a little thicker making it a lot easier to paddle into larger waves. Model consists of a single concave with more pulled in nose and tail in plain shape with extra amount of nose and tail rocker making it perfect for waves at 4-6 feet.
