Shot placement is the key to a perfect pass through, All it takes is a little bone to stop an arrow dead in its tracks. Some of you put down the Rage without even trying them. People like that irritate me...I am trying them this year on my new setup. I hunt with 2 guys that switched to them last year, one is using the 3 blade and the other is using the 2 blade. I tell ya what. Both were pass throughs. One was out to 40 yards and the other 43 yards. The devistation these heads do is like nothing I have ever seen before in my life. It like driving crop sprayer full of paint and spraying it through the woods. Both deer dropped within 30 yards of their stands, to say the least, this was on the same nite. I have a friend here that uses them as well and he contest, that things work like they should as long as the shot placement is good. Rocky did an excellent job on these heads. I cant wait to use mine
