I'm a piper and I wear an 18" horse hair sporran while piping at weddings, funerals, etc. Is it common to wear the long sporran while not piping, or should I just wear my semi-formal? Example: Burn's supper. I'm not going to be piping, so should I wear the horse hair (my favorite sporran) or the semi-formal (rabit hair, 3 tassles with clan badge)?
