As a civilian piper, I don't (and probably will never) wear a horse hair sporran. As Steve (Jack Daw) alluded, that is a military look, so to call a horse hair sporran a 'piper's sporran' is a misnomer.

The pipe band I play with just got some of the 'hybrid' sporrans a couple of years ago - mostly black leather with rivets and a metal cantle. Before that, it was plain black leather with a flap.

When I play privately (i.e. not representing the band) I wear my full mask badger.

So, I guess which type of sporran you choose will depend on the rest of your outfit and how you want to present yourself. Best of luck in your decision.
