The primary function of the mouth is to eat and drink. This is important to keep in mind when we put a bit into the horse's mouth.
Thanks to the function of the mouth, it also has qualities that we should know and think about to find the right bit for the right horse. Do you know, for example, what triggers the horse's swallow reflex?
In addition to the purely functional aspects, all horses are different, they are different in size, convey different feelings through their tongue and can react completely differently to the same thing, for example, a particular bit. Be humble to your horse and listen to it, it shows so much for us if we just are open to listen to them!
It is usually very much talk about the horse when choosing a bit, but equally important is the rider or the driver.
How well educated is your hand? How good are your balance, how do you react in different situations?
Be humble against you and the horse and choose a bit that matches the both of you!
