The reels and spools debate has been done time and time again David. It's old hat now I have to say.
As we know, it very much depends from which part of the globe you originate from as to what is deemed correct terminology for each application of the words.
Look at an any professionally manufactured 8mm 1200ft aluminium spool/ reel box and it will say the word reel on it,..not spool.
It's a wrench vs spanner debate, nothing more, nothing less.
"At least they do here in the UK. "
We are a mere pin prick in the landscape compared to the rest of the world!
A single cell Amoeba among the great vast oceans surrounding us.
I rest my case.
You have the patience of a saint Kevin!
