Truthfully, I have to confess. I wasn't thinking about much of anything. After doing a bunch of serves to do something useful with the time between jobs, I decided to ask if one of the hostesses would video a few. At first she was filming one serve at a time. When I figured it out I asked her to make sure there were at least 3 serves per clip.
But thinking about this, something I realize, if I am going to serve short, I still want the ball to be moving fast. So I want the ball to have a long, low trajectory. It makes it harder to see what spin is on the ball and gives the person less time to react to the ball. And if you can get the ball to skid from the spin/speed issue, the is a much better serve. This also makes the spin/no spin factor much harder to deal with.
When I want to do serves so that someone watching can see the spin, to pull it back towards the net or to curve more, I will serve slower with a higher rounder arc. But I won't do that in a match because those are easier to return.
One thing about those nets, the net slows the ball down so, all of a sudden you have a better idea of how much spin is on the ball as it kicks to the side more and slows down more. But on the ones where they don't hit the net, I have enough pace so that the spin doesn't have enough time to overcome the pace of the ball.
This is useful. Unless I want a serve with a really big curve that is still fast so that it is hard to judge where to take the ball left to right, I kind of want the pace of the ball and the potential skid action to help hide the spin of the serve. All of this means, as low and long a trajectory for the length of the serve in question.
