Skeeter is correct Broadhead tuning is the last step. IMO a good tune starts with putting the bow to spec (timing the cams) setting center shot and nock height. Shoot it through paper followed up by some walk back tuning and then broadhead tune. It takes a while but its worth it.Broadhead tuning is the last step in my tuning process. Since I've been shooting GrizzTricks there's not much to tune.
