Sennoc, ONE forehand doesn't make you a good player. You know your serve has several problems, which I pointed out, so Mr Pollack, go suck your big toe.
Even YOU admitted your game is still progressing, and as such, you are not close to having a good serve....at least not at the 4.5 level.
True, I have not posted a vid of myself, but I can tell you what YOU are doing wrong, and I've already listed the stuff I"M doing wrong.
Nobody is perfect, unless you are already playing on the ATP, which YOU ARE NOT!
I never accused you of being a 3.0, but maybe you have the intelligence of a 3 year old.
