Guideline Grayling Slayer #14

The Grayling Slayer, as it is called, is a well proven highly effective pattern. The idea was to have a small fly with a heavy bead to get it down in the water column quickly. The mylar ribbing adds as an extra trigger point along with the orange collar.

Bead size 14: TC 3mm
Bead size 16: TC 2,3-2,5mm
