I agree with what most people are saying that you dont need the heavy bows to take down north american game species. I would think that 55 pounds would be able to take down anything no problem. I still cant believe what a little tiny broadhead can do to an animal when shot well. With that being said, if you can shoot a heavier bow as accurately as the lesser weight bow i think that you should. In the real world, we all know that arrows dont always go where you want them to and that little bit more weight and power might be what it takes to blow through a shoulder or any other bone that might be encountered. Why not have alittle more power behind you if you can still shoot it accurately.
