I can remember when my daughter was competing in Highland dance, the boys all had sporrans that would, umm, bounce when they danced. Turns out their dance sporrans were very lightweight facsimiles of a regular sporran. The lesser weight and mass tended to be less punishing. You want to see something funny, go to YouTube and look up any live performance of the Red Hot Chilli Pipers doing "Don't Stop Believing." The pop tune alternates with a jig and they all bounce up and down to the beat during the jig. The drummers: no problems. The pipers: no problem. The brass and guitarists: problems. Ranging from stopping after the third hop to one hand on the instrument (minds out of the gutter, lads ) and the other holding down the sporran to spare their sensitive bits. Fun tunes, as well.
