This pattern is super popular in Argentina when chasing Sea Trout.
There is a revered Estancia that owns two lodges on the middle and lower reaches of the Rio Grande named Estancia Maria Behety (EMB). This pattern emerged from this Estancia and has served anglers well on the river for a very long time. This pattern is a tangent, but one I would never be without. A simple but very effective pattern and one that accounts for numerous sea trout every single season
