How long is the lifeline of a bowstring , my bow was bought used and their is light fraying on the string . Is this a problem yet and should i replace it or should i take it to the Merlin centre and see what they say ( probably tell me to replaceit anyway) . In my eyes i'd rather be safe than sorry ,incase it snaps and screws the limbs up .I have waxed the string , but don't want to break my bow after thinkin it will be ok .

are there different types of bowstring , if so whats good and whats bad .
