I'm trying to figure out what arrows I plan to use for 3D's in 2003. I like the light, fat CXL's, but with the factory and Beiter nocks, they get expensive due to damage and don't hold up to nock hitting. To the archers who use the 2213 unibushings, are you satified with them and do they hold up well? Is there any other manufacturer that makes a good nock or unibushing?
