which are the most difficult serves that are very diffcult to return.i know one that is the Ma Lin ghost. if you know any other will you please upload some video of that serves please.
There is no such thing as a serve that will work on everybody. You need to find a serve and work on that serve. Perhpas you can work on two different serves but you then need to get them better, that should be the main focus.
You will notice that most top international players have one or two serves that they use most of the time and they are all different. So find a serve that suits you and work at it.
My preference for myself is the forehand Pendulum serve but that works for me, something else may work for you.
