Me? I personally N-firm upon all lettered firns, but as the H-firn is known in Scotland as a K-firn, it sounded good too.
But then again H stands for "heath" so what's a girl to do?

Anyway, after much deliberation, I'll firnally and firnly decided to stick with H-firn.
And me being wrong won't make me change my mind.

( Hat's off to the Hogmaster. It ain't easy talking in firn talk with only one verb in play. Nice touch, Ted,)
