RE:Flies on steroids
Who said anything about casting these beasts? I figure I'll need to rig a kite to get these any further than 10' from the tip of my rod... I know it's heresy but drifting these from the bow of the boat might be the best option to present them along some of the harbor structure.
I figured i'd try using softex to form the shape of the head. Seemed like it worked well without adding too much bulk like epoxy. I might have to experiment with the gill plate effect that you mentioned. Tie a bit of marabou on each side of the head for some action...
