mainehunt- I shot and killed two deer last year with the exact broadhead you are speaking of. They fly great and in my opinion are a great value for the price. The blades are the exact same blade that rocket uses. You'll notice in the package that the wrench that they send you to tighten the broadhead with says rocket on it. The only thing that I did not like about them is that in both deer I shot I got a clean pass through but lost a blade on each of the broadheads. The blades just don't seem to lock in very well. Outside of that it is great for the money. Hope that helps you!
