I have bought a QZ1-red approx. 1 year ago and was really happy with this ball. And I am going to buy another one, please can you confirm with me that the all the spec. of QZ2 is just the same with QZ1, except the finishing , i.e. QZ1_red is 2000 grit+polish and QZ2 is 4000 grit+polish; so I can alter the suface to make it the same reaction, thanks.
