They are awesome heads. The ONLY drawback is they are hard to practice with. They bend when you pull them out. Luckily they fly like a field tip, so you don't have to practice much. I shoot a Glendel and just pull the arrow through. They make a nasty wound and give good trails. They are trocar tip, so they break bone. Never failed me in the field. Seriously, if they are dirt cheap, buy them and if you don't like them, PM me and I will buy them from you.
