Its been a great topic this one, with lots of interesting info coming to light.
However i was pondering it at some length today at work and you know, i catch very few fish on the river or lochs with the Partridge and orange, despite it often having a place on the leader.
The Waterhen Bloa is a completely different story, accounting for a high percentage of my fish, as does the snipe and purple (or more often than not a Dark Watchett
).
The other flies that work for me in place of the Part and Org are the HE and Plover and a Grouse and Claret (now theres a fly with a good name
). I wonder how much of that is due to insects or personal preference or indeed the water colour
Don't you just love fly fishing
