Yeh! Yeh. Spey cast indeed - a name invented to make someone loadsa
cash teaching gullible anglers the "correct" method.

There is soooo much hype spoken/written about the SPEY cast !!! Any
angler with half a brain will know it is pretty obvious what needs to be
done to retrieve the line and cast in the right direction.

An example of the "naming" of a particular cast reminds me of when I was
a lad. I was performing a roll cast years before I heard the name
"Roll" cast. It just naturally became part of fishing for me.
