nodog, it's obvious you nothing about Tricks or their blade angles
NAP makes a great head, I've said that before, but The Slick Trick is the best replaceable blade broadhead I've used in 40 years of bowhunting.

You could be right. Have been aroundsince they came out and heard plenty of guys complain about their sharpness althoughI haven't for a few seasons. If they are replaceable you wouldn't be sharpening them as mentioned and they don't fit the description. I did use that 2 letter word "if". My point is if you have somethingmeasurable, it takes the guess work out of it. If applied things are quickly eliminated. I could have just described the heads and left the names out From the description people could use the info to determine what a good head verses a bad one according to my O would be.
As far as to their effectiveness, the trickshaven't been time tested like the thunderhead has. Give the tricks a few decades and will see.

I don't know how many animals have fallen and been recovered to the TH, but I'm sure the numbersare staggering.
The spitfires mention were based on a study conducted by someone who tests them. He puts them through hell. I'm sure he's tested the tricks, I just never looked.
