RE: Fixed or Mechanical Broad
Don't listen to them, if they didn't shoot super fast bows or if they could tune a bow right, they would fixed blade broadheads too. Good fixed blade broadheads hold up, both Muzzy and Thunderhead are in that ball park. I shoot 130 muzzy. Go back into the tuning manuals and read about arrow balance and flight. It will tell you for good flight and penetration 60% of the arrow weight in the first third of the arrow! Add that to razor sharp blades on a 4blade Muzzy and you are talking dead anything.
