c903, I see your point and understand where you are coming from. I use three blade muzzy's so I am not one to really argue the point of using large broadheads that leave a devestating hole, but I can see why others use them. I think that as archery hunting progresses there are always more and more "inventions" that are intended to make harvesting a deer "easier" and making the kill "faster", the later of which is where these broadheads come into play. For instance if you are using a zwickey 2 blade you don't have much room for error on your shot and the internal damage created will not be huge but more than sufficient to kill a deer. On the other hand if you use a four blade mechanical broadhead with a 3" cutting diameter then you have a slightly greater room for error and with the extensive damage it creates will cause more damage thus (in theory) cause the deer to die faster. Granted if you are out in the stand you should be able to hit the boiler room with no problem so this should be a mute point. However, as you said, the game animal and Mr. Murphy have a say in the matter so when they decide to speak up it's nice having that little extra cutting room to swing the odds back in your favor. This is just how I interpret it.
