I also duck & goose hunt with my bows. A friend of mine, Earl Bateman(E.W.Bateman&Co.), makes an insert you put behind your broadhead (if you use threaded inserts) called the "Adder" - it adds 8 little cutting edges. It blows a serious hole on impact and usually keeps the arrow from passing through a bird (unless your just too close).
It works a lot like a judo point but won't stand the arrow up if you flight shoot (but the broadhead normally sticks in the mud/dirt anyway). It's incredible on geese here on the Texas coastal prairie!
The "Adder" works great on a regularly fletched hunting arrow as well which makes it great on small game.

You'll notice that I use straight fletching on my full/un-cut FluFlu fletchings- also note that the 6th fletching is missing so it doesn't interfere with the arrow rest or riser window.
The reason I use Zwickey heads- many, many years ago the rep for Zwickey gave us a demo- He was shooting through concrete cinder blocks with Eskimos- it dulled the head but didn't bend or brake it! - I was convinced- I've been shooting them ever since.
