It depends on the shot accuracy of the players your kicking it with really. If he has a good accuray(above 80) it almost always will go straight, i reckon. But with long shots especially, up to 40-45 meters, ( i love scoring from that distance..its always a thrill) i never press the directional button because you never know where its going to go, so i leave it to the player's 'discretion'.
