It really depends on your bow and the amount of energy it is producing. If your shooting a 45lbs recurve I would say deffinetly use a 2 blade cut on contact. If your shooting a modern compound bow at 60+ Lbs of draw weight you can shoot what ever head you want. Another factor that comes into play is your arrow weight, KE, momentum all of those effect your penetration potential as well as head design.
