a plurality of crown turbulators projecting from the crown surface, each crown turbulator having a front portion defining a portion of the crown turbulator being closest to the face portion, the front portion of at least one of the plurality of crown turbulators being at least partly located on the leading edge portion and between the leading edge plane and the rear portion, but not extending beyond the leading edge plane;
wherein;
each adjacent pair of crown turbulators is separate and spaced apart to define a space between the adjacent pair of crown turbulators, and each crown turbulator extends between the heel portion and the toe portion to define a width and extends between the face portion and the rear portion to define a length;
the length is substantially greater than the width;
the space between each adjacent pair of crown turbulators is substantially greater than the width of each of the adjacent pair of crown turbulators that define the space; and
a height of at least one of the plurality of crown turbulators is greater than 0.02 inch but less than 0.5 inch.
