The Barrett’s Bane is a classic/traditional Welsh dry fly, originated by Roland Milton Cosmo Barret. The original has a dun hackle, but I prefer the variegated look of the grizzly dyed dark dun.
Barrett’s Bane (variant)
Hook: Tiemco 102Y #15
Thread: Benecchi 12/0, dark brown
Hackle: Grizzly, dyed dark dun
Rib: Wire, gold fine
Body: Pheasant tail barbs
The prevailing thinking behind this reverse style is that the hackle supports the heaviest part of the hook, and also obscures the point without impeding the hookup capabilities.
This begs another question. Since mayfly duns generally face downstream, do you think the reverse tied patterns with the hackle “wings” facing downstream when fished from above, take more fish?
I call it (variant) because it follows the design of an established pattern, where I deviate by the choice of hackle color - for personal preference reason.
As such - it carries the original name, with the (variant) addition.
