Our synergie straggle is a woven blend of metallic, uv and dyeable fibres.   All our synergie straggle has uv fibres and but  are blended with different metallic type fibres.  The colour range changes as the metallic influence dictates.   For example, red metallics will blend differently to silver etc...  But the different variations certainly give an enhancement to dabblers, boobies, streamers and other lures.
