By simply changing the palmered hackle on a standard Wickham you get a trout fly that works well on summer evenings in fast water. I’ve used this pattern for more years than I care to remember and it has been responsible for many fine trout finding their way to my net.
So, instead of a red game hackle and tails just use a black cock hackle.
Back in Scotland I used to make another variation by adding a blue dun hen hackle in front of the wings. I confess to having completely neglected this pattern since I moved to Ireland 23 years ago so maybe it’s time to give it another swim.
