Will your current bow not go down to 60 lbs??? That' s all you need for Whitetails. Turn that thing down and quit worrying about pulling as much wait as you can stand. I' ve been able to draw 70 lbs since I started shooting a bow and have never hunted with more than 61 lbs. You don' t need it. Your arrow will just be stuck a little farther in the ground. I' d rather shoot slower than not at all. Turn that thing down.
