Question: Which spin is best for first serves?
Answer: It's a good idea to mix your first serves to keep the receiver guessing, but the majority of your first serves will probably have a blend of topspin and slice. The topspin-slice serve can be hit harder than a pure topspin serve, but it still has enough topspin to give it a reasonable margin over the net. The slice component can be used to curve the ball into the receiver or wide away from her.
