So the stroke doesn't change direction until the tip contacts the CB, and then changes direction during 1-2 thousandths of a second contact? That sounds even more improbable to me than what I thought you were saying - but you obviously make it work, so more power to you, Fran.The idea is that the cue is lined straight along the line of the shot on contact and then angles out through the finish of the stroke.
