For me, it comes down to what I am hunting. If I am going for deer, I use a fixed broadhead. You want it to comeout the other side and give you a not only knowledge on what kind of hit it was, but also a good blood trail.
I use mechanicals for say turkey hunting. I don' t want the arrow to go all the way through so having more of a stopping availibility is good.
I' m in the same boat. I use Muzzy 4 blades for deer and Rocky Mountain Snyper mechanicals for turkey.
