Caddisfly Tungsten Beadheads Nymph Head Evolution

Description:
 
Tie fast-sinking caddis nymphs with anatomically molded heads for unmatched realism. 
The Evolution Caddis tungsten beadhead is molded after the common caddis pupa head profile -- round and undersized with bulbous eyes.
Evolution beadheads are simpler to use and have greater versatility than ordinary beads.
The holes are slightly bigger to fit a much larger range of hook styles and sizes.
This extra space is designed for lead or lead-free wire to be used with the beadhead to create better body profiles.
Allows you to create neater flies by hiding excess materials
