Re: Fly for the tropics...
I like it!!!
I can see a lot of fish going for it. If you find a school of Skipjack Tuna or Dorado, something should attack it. I'm sure that a Barracuda would eat that.
One suggestion is not to limit yourself to that color. Make some bronzed backed, olive backed, chartreuse backed, and black backed.
Another suggestion is to put on a red gill slit. It can be as simple as drawing it onto the material with a pen. Or you can tie in a short piece of red flash.
