When to change Dyneema/Spectra stays?

[Norm van't Hoff]

Hi all.

How do I decide when to replace, Dyneema stays? The boat is 12years old with (I have to assume) the original rigging. I can't find anything definitive online, they're obviously vitally important, but it's an expensive decision, can anyone help?  

Many Thanks, 

Norm

The consensus with dynema is around 10 ish years while chatting to a good friend that has dyneema on his Catalina 32. Not sure where he found that info but we were having a dynema discussion because my lower bridled are dyneema.

Herby over on the blog the rigging doctor has lots of info.
