I have doing research on these broadheads (well, as much as I can- there isn't much out there). I was curious if anyone has used these and how they like them. At first glance they look like a gimmick, but the physics behind them are actually quite sound. I have decided to stay away from mechanical broadheads based on my current setup (Cabela's Fortitude, 59# dw, 27" dl, carbon raiders 340s) but I still want something with maximum penetration. The OCD's supposedly have that capability. Please let me know if you have tried them or know anyone who has and how they worked. Thanks!
