Try asking Jurgen about that. He sells them under the name Crescendo.
And Stephen Birkett posted some real interesting high speed photography
showing the stability and response they have compared to standard cloth
punchings... white or otherwise.
If you haven't tried them... well do.

Which begs the question: after all this time, who is routinely
putting in Andre's front punchings?
