Several spinner companies have instructions on how to sand a ball. Usually their first step its to put the label up. What do they consider the label ? Storm has their name, their insignia, and the ball name on their balls. Radical has company name and ball name, DV8 has the ball name and their saying on the ball. I had one pso tell me to start with the grip on the side and then do the usual rotations. I used to start with my grip up. How do you do it and is there a correct first step ?
