Guess that I didn't think about the string that much, my OLD DARTON has a plastic cord type material covering about a third of the string, and my steel cables are plastic coated, it's still the original string, and yes I shoot he living daylights out of it.. the copper noc on my string has torn the daylights out of my release is the main reasonI'm asking. of the loop is even close to the copper noc, then I want to save 50bucks on a new release.what is the difference in noise and speed between the two? and any other pros or cons between them
