I started out using Thunderheads, switched to Rage and then went back to a fixed blade-- G5 Striker. For some reason people get really defensive when the subject of Rage broadheads comes up. I'm just letting you know what my experience with them was.
In the process of taking my arrow out of the quiver and nocking it, many times the blades would open. Which made me nervous that the vibration from the string might cause them to open in flight. Now a lot of guys will say it's operator error or whatever. That's fine.
My thinking is simplest is almost always best. The nice thing about the heads i use now is that I just don't think about my broadhead at all. There are plenty of other things to worry about when a buck is walking into your shooting lane!
