Has sythetic rigging been around even as long as a decades old failed rig??
What warning signs od fatigue does it give??
No it hasn't. Synthetic line still hasn't been proven for 10 years plus. But if it starts to get fuzzy or frayed, you usually have time to change it out (at a fraction of the cost). It just takes more attention from a maintenance standpoint. SS rigging might show a meat hook, or it might not, and just decide it doesn't want to hang on anymore.
