Have to disagree with you. The ONLY way a full is not strong enough is if you hit something you should and even then the arrow will be toast no matter what head your using. Being full or swept has nothing to do with it.Swept are more forgiving, full can be shot in all states. Fulls are not stronger, as they have same amount of steel where the blade ties to the ferrule, also on a full if you hit something hard it can bend the blade into your arrow ruining it, not an issue with swept. Overall if legal the swept is the way to go, otherwise, the full shoots well and kills'em just as dead.
