I understand what everyone is confused about.

I know when Bill from zippers saw I had a FF string on, he was really alarmed and told me to immediately quit using that string. He asked how many times I have shot that bow with FF on. I expalined 3-5K shots.


I think bill knows what he is doing, but the proof was in the pudding. I shot lots of shots with FF and the glass just began to crack. It could have cracked with dacron.
