Great Pattern for the Grayling and trout tied using Top Quality hooks, materials and Beads (Bidoz) you can't go wrong.
One not just for river fishing but for the Still-waters also when allowed to use Tungsten beaded fly's or weight.
I've been catching over the last 5 winters with this pattern on my local rivers.
IMPORTANT as I tie all these flies myself there is normally a wait time of up 10 weeks so please make sure you leave ample time when you are ordering. If you require them quicker then please contact me first.
