I've just gotten back into archery after a 20 year absence. That said, man have things changed. Anyway for my question, I've been shootin 4" quick spins with a wisker biscuit and I've recently read in a few places that is not recommended. My grouping is not bad as I'm gettin back into it but it aint nothin to write home about either. Have I violated a cardinal rule or is that combo ok?
