The reason I am against mechanical broadheads is this. Anyone who says that penetration of a mechanical broadhead is equal to a fixed blade is wrong. If you tune your bow properly fixed blades fly the same as field points, or mechanicals. Why use mechanical broadheads? If the bow is properly tuned they fly no better and penetrate less then fixed blades. They are a fast fix, for not spending the time to tune. With that said, when i say be ethical i do think that most people that shot mechanical broadheads are not eithical. There are many of you that are ethical, you have the ability to properly tune your bow and the ability to shot it well. Why you use mechanical heads i don't know but that is another story. The reason im against them is simple most people who use them, use them so they don't have to spend time they are lazy.
