In reply to Jack Geldard - Editor - UKC:
Nice article Kevin, and thanks for posting it Jack.
Just a small point, but those Japanese cimbers call themselves the "girigiri" boys, not the "gri-gri" boys. A rough translation of the Japanese "girigiri" would be something like "at the limit". In that context the name makes a lot of sense, so you ought to correct it in the article.
Cheers
Tony
