Here's a link to a broadhead test, that tests various heads. Not as in depth as 5shots reviews, but it has an amazing accuracy test where human error is emliminated. That's the only reason to watch. You may have to skip the first part of the video, i did, it has nothing to do with the test. It's small and on the left side of the screen. Pretty neat stuff
