I personally prefer full cut on contact broad heads. But with fast bows above 280 fps you will most likely have planing issues. I used to use Bear razor lites in 100 gr. But no longer available. So in search of a new head I chose the magnus stinger in 100 gr. I really like the design of the magnus broad heads. The back edge of the blade is sharpened like the leading edge. So if you don?t have a full pass through and the arrow is working it self back out it?s cutting tissue. I just picture that head slicing and dicing while the animal is running. I did have some planing issues with the Magnus stingers due to the long blade. But have bought the Magnus black hornets and am very happy with the results. 440 gr. arrow flying at 292 fps. And yes like every body else says about their broad heads flying like lawn darts these do the same thing. There?s a YouTube video of the top ten broad heads and the Magnus black hornets came in 2nd. 1st was a mechanical due to accuracy. Also Magnus has a lifetime warranty no matter what happens to the head. I?m not sure about other broad heads, but after tuning my broad heads with the main blade vertical to my string. I can take any broad head (Magnus)and switch them from arrow to arrow and the main blade always lines up with my string. That proves to me the quality of machine work for consistency. The Magnus broad heads are extremely tough too. Last year made a bad shot and deflected the arrow hitting a chunk of steel plate. Arrow (maxima red 350) blew apart into 3 pieces and the broad head stayed mostly intact. Pretty impressive!
