I'm glad this thread came up! You see, I have been sort of a broadhead junkie since 1973! I have used Bear Razorheads, Ace Standards, MA3's, Bodkins, Snuffers, Woodsmans, Magnus I and II's (with and without bleeder blades), all kinds of replaceable blade broadheads (back in my wheel bow days), Grizzly's and every model of Zwickey except the Cliff. The only reason I ain't used them is because they are illegal in N.C. I even completed my "Zwickey Grand Slam" on deer this year.
The reason I have used and tried so many different types and styles is that I don't shoot heavy bows and I'm always trying to balance penetration with cut size (making heavy bloodtrails). Always looking for that "perfect" broadhead! Well, guess what? There ain't a "perfect" one! If you get a great bloodtrail with one today, you might not on your next shot. I used to think a big, nasty broadhead would/could make a difference on a gut shot. It might, but waiting long enough before taking up the track has helped me recover more deer. A broadhead that blows through the rib cage on a broadside shot not might not give enough penetration on an angled shot. An exit wound helps with blood on the ground.
So what's the answer? Pick a good, solid, COC broadhead that flies great from your set-up, that YOU can get sharp, and practice with it so you have confidence in it. For me that is a Zwickey Eskimo or No Mercy, Magnus II, Grizzly or Ace Standard. (sorry for the rant but we are snowed in and I'm already having a touch of cabin fever!)
