Hi Leon, Your question kind of vague here.
You ask ........Does it make any differences for bowlers playing
spinner???
What are you comparing with? or you are asking various spinning
techniques applied by spinners and thier differences?
Well, there would be, otherwise there would not be the
variations..... right?
As to which is better, its really up to individual's
application of the techniques, practice makes a person's more
confident with his skills and knowldege over a period of time.
I can only say a good spinner does have a distinctive
characteristic style of his own, and he keep practising it until it
reaches a level where he/she evolves into his/her
trademark, only he knows why he do it that way, and that should be
the reason why there are some differences when you examine
different spinners bowlers.
Cheers
