rage heads are good, but they will come open in a quiver and you need to check them often to make sure the are "tight" I have killed several deer with them and they did the job. I have also killed several with slick tricks and they do just as good a job, but are more durable and fly almost as well from a properly tuned bow. If they bow isn't tuned that's another story. This year I have tried the NAP Killzone. It's similar to the rage in size, but the blade retention system is more like the spitfires. They fly great, penetrate the same as the rage heads, are a little sharper and from the two deer shot with them this year (same arrow and broadhead) more durable. I have not run them through my old broadhead tests but based on what I have seen there score would be similar to the rage probably slightly higher because of durability but very close.
