1. A golf ball with a plurality of dimples having an aerodynamic coefficient magnitude defined by Cmag=√

  • (CL2+CD2) and a percent deviation Cmag=|(Cmag1

    Cmag2)|/((Cmag1+Cmag2)/2)*100, wherein CL is a lift coefficient and CD is a drag coefficient, wherein Cmag1=Cmag for a first orientation and Cmag2=Cmag for a second orientation, and wherein percent deviation Cmag is about 3 percent or less over a Reynolds Number range of about 69000 to about 230000.
