How do you test sticks?

Most sticks come is prematched pairs that are roughly equal in weight and balance. The weight of unmatched sticks can be tested first by feel, and secondly by turning both sticks around, striking a hard surface with the butt ends, and comparing the tone of both sticks. Closer tones indicate a pair similar in density and weight. Unmatched sticks should be rolled on a flat surface to separate warped singles from straight singles. Never use sticks that are warped or show irregularities in the wood grain.
