So I have Alfie (a purebred Arabian gelding), and my barn is having a large event show! I want to do halter, but I've never shown in it (I'm also new to the showing world). Since it's just a little schooling show, what type of halter should I use? I have a Parelli blue rope halter, a Weaver black and blue rope halter, an older black with white stitching nylon halter, and a really old beaten down purple halter (I don't plan on using this lol). Could I use one of those or do I need a specific type?
