I am shooting the NAP 2-blade Bloodrunner. Unfortunately, I have not been able to put one through a deer yet, but it really tore up a coyote last week. Entry and exit wounds were huge. I also recommend a illuminated nock for your arrow. My eyes are not as sharp as they used to be, and with the fast arrow speed of crossbows, I have a hard time following arrow flight. The illuminated nock made a world of difference for me.
