Make an attempt to smack up (traveling from 7-1 o'clock) on the right half of ball with pronation ...this gets ball spinning counter-clockwise and strangely generates more pace than smacking the back of ball ...do not simply brush up 7 to 1 ...you gotta smack it with twisting right arm using the left side of the string bed (ok, that's probably not what happens ...but it FEELS that way)
