Yolk,
I think you are definitely right on about the grass carp and tilapia!
I know where there are some HUGE grass carp swimming around, and the new pellet fly will work pretty good on 'em!

Steve,
Welcome to the forum. How about you figure out how to post photos and start a thread with some of your fish pics! I am anxious to see them, because if you invent a pellet based fishing lure, I am guessing you know a thing or two about feeding fish.
