Yup, just go with what you are comfortable with. Its not a contest to see how much you can pull back. If you can pull 60 or higher and you are uncomfortable in doing so, you are at a disadvantage. Also, weather can play a part in it too. I could pull back a great deal more in warm weather as opposed to cold weather. 50 is plenty, and if thats what you are comfortable with, stick with it. As for the peep, they can be taken out or put in pretty easily but make sure if you dont know what you are doing to go to a pro shop or ask someone to show you how. Good luck!
