Two trusted answers right there.
I was shooting a bow with an excellent, fairly new string a while back. Noticed the serving was looking a little sloppy, but shot it some anyway.
Woke up one morning to find the bow, which usually hangs strung on the wall, on the floor.
String broke by itself in the night. It's a wonder it didn't break while I was shooting that same day.
I'd read Pearl Drums and LBR's input again, and play it safe if you're in doubt. And it's not only the bow that could be damaged... a bow blowing up in your hands is no fun whatsoever.
