There are so many different broadheads it's hard to pick just one. Take a look at my website, and read through the mech vs fixed as well as the new heads section. After you do that drop me an email or Pm if you have anyquestions. To be honest I can't reccomend any heads without first knowing what type of bow you shoot, poundage and your draw length. Kinetic energy plays a big part in choosing a mechanical broadhead, as well as bow tuning. I would also suggest you read the ratings page so you can understand the scoring system.
