i've shot deer with muzzy 3 blades, rage 2 blade, nap hell razors, nap thunderheads. They all killed my deer the same. i liked the rage the best because they fly just like my field points. No BH tuning needed. what i don't like is the price, and the blades are trashed after one use. i want to try some grim reapers or spitfires this year though.
