Just like most everyone else has said. If I do my part the broadhead has always done it' s part. I used the shockwaves last year and had good luck with them. Two deer were down within sight of the tree and the third made it about 35 yards just in the trees where I couldn' t see it, but I heard it go down. My buddy remaked wow! a blindman could follow this blood trail just by the smell of the blood, and if he could follow it anyone could. But, that was an excellent arrow placement with a low exit wound and all of the blood could drain. I find the secret to heavy blood trails is to have that low exit wound thru the vital area, doesn' t really matter which broadhead is used.
