Cheap muzzy MX-3s. I have tons of broadheads, but me and my buddies only see the big bucks when one of those is knocked up. Can't explain it, but I'm sure not going to go against it.
I have had success with various mechanicals over the years and won't knock em, but I prefer my fixed blade slick tricks standards or magnums. They poke a big slug hole in both sides of the deer and they go down with a nice blood trail. Others I would not hesitate to use would be QAD exodus or Magnus Black Hornets
