This is the premium "dubbing on a thread" product in the Semperfli range.
What makes it unique is the additional metallic strand woven through Quick Dub. When you wind Quick Dub over a body its magical feature quickly stands out. The metallic strand quickly appears as ribbing along the length of the fly. Simple and deadly flies can be made rapidly with just a few strands of grizzle hackle for a tail, some cdc as a wing or a hackle of course all tied with Nano Silk!
