The 70# Duallys are stout. But I see no reason to shoot more than 60# with one of them.
Many people ask me why I shoot over 70# of draw weight. My response to that is I prefer to shoot a heavier arrow at greater speeds to increase KE. Since I only hunt and do not shoot competively, the extra draw weight is not as big of a concern to me. I can comfortably shoot 70+# of draw weight. True you can match the speed of a 70# bow with a 60# bow, but for hunting I prefer to have that extra punchthat I get by being able to shoot a heavier arrow faster.
