72# Because my bow is 60-80# and I was told it's best to use your bow at max poundage but I could only manage the 70# but settled finally on the 72# because the arrows flew so well at that setting. It was a little tough the first year and had trouble once or twice during cold days but I've been shooting it that high for so long now it doesn't seem much at all now. I usually shoot 25 arrows a day getting geared for the season and 50 or more as it gets closer. I'm about average build but because I use these muscles often that they get stronger. Ego never entered the equation, at the time I thought I was pulling lighter than most guys.
