invention they preferably comprise about 40 or less of the ball surface more preferably about 30 or less about 20 or less or about 10 or less the lower percentages are more preferable in cases where the channels are combined with other types of surface texture such as conventional dimples the combination of a relatively low coverage of the ball surface i e about 40 or less and relatively steep edge angle i e about 16 u00b0 or more provides a unique aerodynamic package for golf ball 10 of the present invention that cannot be achieved with conventional circular dimples alone preferably channels 14 have an edge angle that is steeper than edge angles for conventional circular dimples in one example channels 12 have substantially the same depth as conventional circular dimples but have a width that is significantly less than the diameter of conventional circular dimples causing the edge angle to be steeper than the edge angle of conventional circular dimples which typically ranges from 12 u00b0 16 u00b0 the edge angle of channels 12 is preferably greater than about 16 u00b0 more preferably greater than about 18 u00b0 and more preferably greater than about 20 u00b0 the edge angle can range from about 16 u00b0 to about 90 u00b0 preferably from about 18 u00b0 to about 40.
