These are tied by a local VA fella. We use these flies for ALL sorts of species, but our favorite are bass. Striper, smallmouth and largemouth love a Half N' Half, and those who fish the salty seas are used to chucking them at Specks, Blues, Flounder, and pretty much anything that eats a little fish (which is pretty much all bigger fish). 
Grab you a few handfuls cause you're gonna like what you get.
