A big fat Delta is hard to beat. Easy to sharpen,
and they punch a big hole in whatever you hit with them. I have used them on wood, aluminum, and now carbon shafts.
Some years I get a package of something different,
but on opening morning of bow season, Zwickeys are in my quiver. I currently have seven battle scarred veterans ready to fly this year. All have killed at least one deer. My practice heads are ones where the blades are nicked too badly or something. If I`m lucky, next year I will need a dozen newbies to get trianed.
