hi everyone, im a high school singles player, and i havent been playing very long (just 1.5 years). traditionally i serve long, and just serve short every once in awhile to throw my opponents off (esp when they start standing 3 steps backwards when receiving). unfortunately my deception is quite poor (as my teammates constantly complain that its too easy to read my serve). when i hit the long service, i let the birdie drop to nearly knee level, and then bring my arm back for a large upwards swing when i hit the short service, i let the bird drop to about waist level, and then decelerate my arm, bringing it across horizontally. is there any way to make it so that the form is the same up until the point where the racket contacts the bird? any videos/pics would be greatly appreciated!
