Yan,
I think it is pretty simple... if u hit through the ball more (doesnt matter what grip), it will
go more towards the red path. If u hit through lesser with more bottom to top sweep (topspin),
it will become more like the green path.
Another thing is the follow through... if u close down the racket face after the contact, spin
would lessen. If you windshield wipe your follow through, spin would increase.
Racket face on contact, contact height & takeback also play a major role... damn.. come to think of
it, its not easy also.... LOL.... so many things to take into consideration.. minus gear somemore,
LoL.... no wonder its a life long learning process eh?
Well thats why when u go coaching they'll load up your stroke memory with repetitive
stroking everytime... they keep correcting & fine tuning & build up your consistency. But I
foresee that your stroke would become more like junebug... slightly more on the flat side but
the difference between you & him now is movement & control... junebug can move very2 well & has
great footwork prior to contact. You will know a player moves well when he execute inside out
forehands consistantly... thats one of the more difficult forehand to prepare.
Watch more when june is hitting with chip73.... they're the better players here

you are so right Z, that's why sometimes though i get tips and guides fr other coaches fren but i find that probably it's due to the drills and consistent ball feeding to build on the repetitive muscle memory thingy.. And one thing i definitely don't have is footwork. like badminton we always have certain footwork that we follow for court coverage not just moving body towards the ball. but in tennis i never get around learning all those footwork drills... mmm... but i agree with you also that it's a life long learning process for e.g. even from those conventional strokes to the modern style of playing now. damn .. now i'm really serious in getting a coach to once and for all set me straight on my basics. from there maybe i can move on and coach meself ..hehe.. but fundamentals need to get it right.
