Cyclone hit the nail on the head...... SHARP ONES. A 1 1/8 3 blade leaves the same blood trail as a 1 1/8 3 blade.
(If they' re sharp) Different animals... different hits.... it all factors in. SHARP and placement are the key to any blood trail. Don' t worry so much about, is there a particular one that makes them bleed better. Worry about is it sharp and does it shoot well from my bow with me doing the shooting.
