Sculpting Flash Fiber is the ticket if you tie baitfish patterns. It come in a mind blowing color pallet that conveniently incorporates micro flash. It is the material that Jonny King uses in his Kinky Muddler series that incorporates a saddle hackle tail with the trimmed Sculpting Flash Fibre head. This tying method can be adapted to imitate thin to wide bodied baitfish as well as crab and shrimp patterns depending on your needs. The resulting flies are light and water resistant so they cast well. Great material!
