It's easier to get slice serves in than it is to get flat serves in. Why is this? The ball's spinning sideways, which makes the ball curve to the left (for righties), but does this spinning action, also, give it a little downward motion? Or is it that the balls spinning in this way tend to float a bit more, giving it more time to pass the net, before it dips? Which of the two is it? Or is it a combination of both? Or am I wrong and it's not easier to get slice serves in (I'd swear it is)? Just curious. Edit: After posting, I read this and, now, they kind of sound like contradicting explanations. Someone enlighten me, please.
