RE: expandable broadheads
Which mechanical is best depends on your specific setup and exactly what you want the head to do. Do you want a huge cutting diameter and do you have the KE for it, or do you want great accuracy and penetration like a fixed blade head? With some more specifics I can recomend some good heads for you to try.
