Extra bright flies really do seem to work extra-well in the cold water season. Not that they don't work well in summer too. But in winter they're a bit like magic. Give them a few days of fishing and see for yourself. I'm a believer....not a trace of doubt in my mind.
...Oh god. That's an annoying song from the 60s isn't it? But it's also a damn good fly.
