this rubber is fast and spinny really good for looping but hitting alway go long ,i have about 2 weeks and i play 2 time a week but still not get used to it .every time i come up to smash to finish the point and alway go long eveen i close the racket i recommend the calibra lt sound is much better for looper and hiiting ,countet loop is really good i will go back to calibra lt sound .
