I personally am not a fan of ANY mechanical broadhead. Just something to fail when there are so many other things that can fail. Rock has about the best point about these Dead Ringer Freak Nasty broadheads that you can get. People don't seem to think about the fact that 90% of archers today hunt from elevated stands. If you don't get full penetrating pass through performance, you are more than likely going to be doing grid search for a few hours to find your deer. I've also see WAY too many "glanced" deer from mechanical hits from angles that a fixed blade cut on contact broadhead would have bored right on through. When shooting at a quartering away deer from elevation, you not only have to worry about shoulder penetration, but also sternum penetration and that sternum can be a tough monkey to get through!
