In-regard to the "deflection". Well, deflection IMO is when you hit an animal on a hard angle, and the arrow changes direction. I've shot a variety of mechanical heads, mostly large cutting diameters, and have never had this happen. Most of my shots have been quartering away shots. For the record, it can and does happen with fixed heads as well. You never know what you may hit in the perfect spot, perfect angle, which could result in a lost animal. Look at the monster Pat Reeve shot with a Muzzy up in Wisconsin. That buck should have been dead as Pat smoked it. He hit a rib just right, which deflected the arrow up between the rib cage and the front leg. A gun hunter ended up killing that buck later that season. Is that considered a fixed head "failure"???

I very rarely get a pass-through with my set-up. Most of the time I get through one side of the rib cage and bury it into the other shoulder. I don't care if I have a pass through if I hit an animal where I aim, which is the whole reason I use Mechanicals in the first place. When you are pushing 1-3/4" diameter of destruction through any big deer, it will absorb a ton of energy. I don't worry about less penetration. IMO, using every ounce of energy is a good thing, unlike pounding a deer with a tiny fixed head where you blow through cutting very little tisue in the process. That is a waste of energy, unless you count the ground on the other side of the deer as damage???

I enjoy following very short bloodtrails that would make some people sick. Blood spraying 10 ft. out the side of a whitetail is the greatest feeling in the world. Fast humain kills are the name of the game. I use what I believe delivers the fastest death blow possible.
