All the points mentioned will work. Actually, any field point can be turned into a bunny buster with the addition of a small washer behind it.
I prefer the regular blunts, as they are cheap, go through the brush with less hang ups, and hit pretty hard.
In past years, people have come up with some down right wicked heads with stuff from the local hardware store and blunts or field points.
They all are fun to fling at em.
