Hi Rob
Great stuff ........ all views are good.
I've never banned anything for being too successful ( I want folk to catch plenty of fish
) It is the spinner blades and prop blades that I have a problem with, they are not going to do the inside of a fish any good.
In this case, both types of "fly" are very clearly a "spinning tool" to my eyes ........ you are right, there are many other types of flies that are difficult to class as "flies", but that is a huge minefield of a topic by itself.
Another "fly" that I would ask anglers not to use please is the one widely seen in magazines last year with plastic "wobble cones" mounted on the front like a rapala. I just see the plastic cone shaped thing as something else that could harm a fish.
But we digress ..... if something is against the fishery rules, there will be a reason, so please don't ignore the rules.
Best wishes
Mike
