With a Morgan, you can use a leather halter with a stud chain ONLY if you show him in western attire (you're dressed as western). You can't use an Arab halter, those only go on horses that are Arabs. You can use a bridle (any English bridle and English only, no western bridles, just western halters), but yes, you need the cavesson. If you show in a double bridle you will use the cavesson and only the curb bit, you don't need the snaffle.
If you have anymore questions just ask, I show Morgans.
