You made a fine choice. You do not have to have the rope cocker, but it will make it better. If you do not just mark the string like Dan said and you will be good to go. If not and the string is off, the arrow will go all over the place. The scope is a must for me, but like others have said, maybe not for a eleven year old. The pin and peep will work great, but the low light buck thirty shots may get ya. Good luck and keep us up todate!
