I used the big Thunderhead three blades for years when I used a compound. They usually left lots of blood.
When I went back to a recurve, I started using two edge heads, and noticed my arrows passed through without even slowing down, and the blood trails were not noticeably different for the most part. I also found out that the skittish Michigan whitetails didn`t run nearly as far before they stopped, when I began using two edge heads. My recovery distance went down drastically with two edge heads. They usually fall within sight, or at least hearing.
A big, easy to sharpen two edge is my favorite.
If I could get a big Snuffer as sharp as a Magnus-1, I might think about trying them.
