I have an 8' single rein and it is the perfect length when riding my horse in his hackamore (long shanks). Now I have taken to riding him in an O ring snaffle and the rein is much too short for that. So I will be buying some new reins and the style I like only comes in two 8' split reins. I am a mess with split reins! What would be the best way to to attach the reins together? I was thinking of punching a hole in the leather and attaching them with a conway buckle. It seems to me like I've seen that done before. Does anyone have suggestions?
