What type of bit is most recommended for hunter under saddle shows?
The AQHA rule book shows very clearly what type of snaffle bits and other bits are allowed in your HUS classes. I would read the book to be certain that your bit will conform to rules. A simple D snaffle is probably the most common snaffle, an O ring is also very, very common. I don’t see many egg-butts but they certainly are allowed. Kimberwicks of both sorts are allowed but fairly unpopular at this time with most trainers, as the feeling is a HUS horse should move on light contact and be forward, and the leverage action of a kimberwick can stop that for many horses. As for the type of bit with a D or O ring, once again that is very specifically shown in the rule book. Plain smooth, slow twist, french link, all are listed and state whether they can or cannot be used in Junior or senior horse classes. I no longer have a current AQHA book, but I do have a current APHA book, and it will not allow certain snaffle bits to be used on junior horses, and it clearly says how big the O is allow
