Received my new Klippermate today but a quick question or two before I start using it. My racket [organix 10 325] has small pieces of leather between the strings and grommets in the throat area. Can these be reused and what is their purpose. Lastly my current string job has tiny pieces of string between the grommets and knots. Should I look to replicate this set up? Thanks guy's, I don't want to mess up.
