do you have access to taped pba shows ? if so, watch walter ray williams, jr., and norm duke when they are going straight from the outside line. these are the best two players in the world at this shot. they have several things in common: lower rev rate, higher ball speed, end over end roll( 20-30 degrees axis rotation ). accuracy and speed control are extrememly important. the oil pattern will dictate whether you can play this type of shot.
