Heres a test for you being you already have em fletched up. Does the strong helical fletched arrow spin enough to bend and or break broadhead blades off on impact?

When I was using the Aerovane 2's, I was using 2 blade Rage extremes. Every arrow recovery at least one blade was broken off. I havent used the AV'2's in a while and the thought just came to mind.

Wow Yelpy, first I have never heard of such a thing, never even considered it. It would take a massive amount of rotational energy to bend a VPA blade. Both deer and the blob target have never done that. The last 10 years or so I have been using swhackers. I have bent but never broken any blades with deer. In the blob I have never even bent a blade but seldom have I shot a "live round" most always shoot the practice head and again no bh damage after countless shots on same head. I do shoot arrows with the helicals often enough to know. As for the swhackers and deer I just always assumed the blade bending was from others sources not the rotation of the arrow but.....IDK you might be on to something.

Just a thought. Never tried to prove anything myself but it came to mind when I was reading rt's post and just thought a test might be in order. I just dont have the time to play. Momentum comes to mind. When the arrow starts spinning how long does it take to get up to its fullest rate of spin and how many revolutions say per second will it be spinning at its highest spin rate? Im sure Dorge had done tests amoungst others. The long blades if open before spinning has slowed on a mechanical head might not be able to handle the force applied to the sides of the blades from the arrow spin when entering the animal.
