This product was developed by renowned USA tyer, Steve Farrar and is unique in the fact that it is already tapered and you can tie a fly using only the SF Blend. This material is a perfect blend of our Slinky Fibre and Slinky Blend range with a fine mylar flash. The BLEEDING colors incorporate a red and wisteria color flash. The MIDNIGHT, VIOLET NIGHT, PEACOCK and HERRING BACK have a wisteria (dark blue/green). The rest of the colors have a pearl color flash blended in. UV flash can also be incorporated into any color from this range.
