I recall the WF and CF range of rods, my old trolling rods (bought some 30+ seasons ago now
) were Daiwa CF9812B, the 'B' range in CF98 were specifically ringed and tweaked for trolling and harling in mind, but I have no idea what the 'A' was for on the WF range. Magnus might know.
From memory, I think WF was whisker fly and CF was carbon fly?
So yes, exactly that and....
I also have a 15 footer - does anybody know what the "A" in "15A" stands for?
Nope, but I would be intrigued to find out
I might speculate it was an early reference to 'Amorphous' which was, I'm pretty sure, the successor to WF.
