I'm betting that your foam wings will catch so much air that they'll be pretty much uncastable on any tippet.
For a dry fly, you might try a foam post with a parachute hackle. That's not going to "helicopter"
Other wise try tying your foam down like the shell back on a humpy
You could actually do both at once on a parachute humpy
OK, After a design flaw adjustment. Hopefully it will resist leader twist.
