I'm not going to say they are the absolute best head on the market. I don't like testing alot of different heads on game to see if work well or not. I have taken 4 deer with my razorbak 100's. 2 went down within eyesight 30yds or less, good hits. Other 2 weren't perfect hits, but both died & recovered within 100yds. I have yet to loose a deer using them, and like said had 2 that hits weren't like I prefer, but did the job well. How can you ask for anything more!!!!
