I've been experimenting a lot with my tosses, and at least to me, I find it easiest to serve when my toss goes only slightly higher than the contact point with my racket. In other words, I try to aim my tosses so that the zenith of their trajectory is only a few inches higher than the contact point with my racket. I have tried higher tosses, but I think it's more difficult to coordinate the contact with my racket when the ball is travelling faster down. So, I try to toss the ball only to a height from which the ball would not have gained much acceleration when it meets my racket. In that regard, is there such thing as the ideal toss height or is it or individual? I've noticed that pros send their tosses really high. What's the benefit in that, because I think I can still manage the full winding of the body while the ball stays up in the air for considerably shorter amount of time (but then again, pros may wind up far more, requiring far more time before the ball comes down to the contact point)?
