stick with the rubber bands unless you have a bow thats super fast they will be your best choice, one of the best I have found is rocket steelheads they are slightly smaller and blow through deer, they also come with enough rubber bands to last several year, unless you shoot your heads into target in that case use the dental floss.. I baught 6 steelheads about 5 years ago and still have rubber bands left over, just change them out every season or when one gets damaged (hardly ever)...goood luck
