Tedder, Going through various boxes of clutches hoarded over the years,(some from you) Metal clutch plates——I have a set that appears to be dimpled and other sets that are smooth. Preference? Did/does Barnett make both heavy duty and “standard” clutch pack springs? How to visually tell a heavy duty spring from standard? Getting ready to replace clutch plates in my desert race bike.
