That is a great looking fly.
Have you seen the Globster Fly By Drew Chicone?
In This Issue: "Number 100!" Celebrating 100 Free Step-By-Steps and the 100th Issue of the Salty Fly Tying Chronicle! "The Globster Collaboration" Once a closely guarded Abaco secret, now revealed! Learn to tie Clint Kemp's and Drew's ultra-realistic baby lobster imitation.
This globster fly was working very well for Bonefish for me. Size 4 and 6 hooks. Drew has an interesting story behind the making of his fly design collaboration, which you can read about in the link above if you are interested.
What are you using to make the antennae and claws?
What have you thrown it at? Any success with this fly yet?
Have you used this as a crawdad imitation for bass or fresh water species? It looks really good to me!
