I tuned my arrows with cheap aluminum Easton inserts, got the field point that shoots perfect tune with my bow, then mixed and matched iron will inserts, collar s, and broad heads that added up to the same weight. My big game broadhead is different weight than my turkey broadhead, which is different weight than my small game heads and blunts.
I have 3 different setups with 6 total different components and they all shoot lights-out.
