Hey Slicepong, yes I would still try to aim mid court for a half long serve but just with slightly more follow through or a very slightly heavier contact. Not a rule bit just a good way to judge where you need the ball to bounce to kae it easy to repeatedly get them consistent. Yes thats very true as well, if you can serve short and but with the ball landing near your own white line this is great for disguise, it takes practice and very good touch but definitely worth practicing as your serves will be much harder to read.
