Horses are as different and diverse as people, which is why everyone should know and observe their own horse closely. Once the correct size and thickness of the bit have been determined, the rider is now faced with finding the right shape with the correct snaffle rings. The starting point for many trainers is the single or even the double broken water snaffle. In general, if you determine that the bit is not suitable for the respective horse, you should identify the problem and try others that might adress that particular area. There is no right or wrong, but it should be targeted individually at the rider and horse.
