Horse tack. Nosebands – how tight is too tight?

Standard equipment in English disciplines. Training equipment in western. While nosebands are designed to prevent bit evasion, in the horse business, we’re inclined to default into thinking “If a little is good, more is better! Glad to see that Equestrian Canada has added a 2021 horse show rule addressing nosebands. The question upstream from noseband “restrictions” – are we masking bit evasion without asking WHY the horse might be resisting?
