One of those links strongly suggested using Balsa USA Gold CA (thick) to quickly and strongly glue the foam together.

I just ordered some from the Balsa USA website, after discovering our local "Michael's" craft store didn't seem to carry it. This glue is supposed to be waterproof and also set up quickly, which would make this fly much more enjoyable to tie (rather than clamping and waiting for hours).

I can't wait to give it a shot, it should work really well for largemouth bass, white bass, hybrids, and probably smallies. I caught a musky and plenty of northern pike on a Rebel Pop-R topwater, so I don't see why they wouldn't hit this fly too!

Thanks for posting all the links, guys!
