Have a bow I've had sitting in a case (Bear Encounter) . Had it re-strung about 5 or 6 years ago and then bought a new Matthews, so the Bear has just kinda sat. Planning to give it to my nephew who's just getting into the hobby. String looks good (I mean...it's brand new), but having sat for 5 or so years, should I have it re-strung or think it'll be fine?
