Hi,
I first came across the Blue Elver almost thirty years ago when I was on the Isle of Lewis in the Outer Hebrides.It is I believe an Arthur Ransome Fly ?
However we always fished it as a dropper when loch fishing.As an attractor fly,
most of those salmon hooked came to the elver normally as the fly surfaced and created a wake on the surface,as the angler drew into the backcast.
Many a time I witnessed salmon chasing and snapping at the fly resulting in hard takes..
Other times short lining from the boat fish would rise almost immediately to the dropper,striking as soon as the 'boil' at the elver was observed [ before feeling the fish ] ensured a solid hook up.
The most successful salmon fly I ever used or seen used for salmon.
'Dibbling the fly' in the river is just as successful.
