Butch, your post reminds me, did anyone catch the last episode of Deadliest Catch? The one where the CM was snapping it's lines at the dock in high winds. . . Anyways, the big Blue I'm assuming Amsteel slings were the ones that were popping. You could see the older poly rigging flex, and the blue lines would just pop apart. Just a real world demonstration of what we already knew. . .
