The heaviest and lowest flying Fujikura Rombax iron shaft made weighing in at 115 grams. Designed in mind for the higher club head speed high ball hitter, the shaft speaks for itself when you feel the raw pureness at impact. Itís like a hot knife through butter, a laser through steel, or, you know what I mean. Low spin and low launch provide an excellent penetrating trajectory. Can you say hole hunter? Flexes come in stiff and extra stiff.
