Thanks Tim. I always thought 5-1, but the manufacturer is the place to go!

I always thought 5 to 1 also for rigging.
Do all exotic fibers go to 4 to 1?

Mark and Norm, I was wondering the same thing.

I wonder if the different manufacturers have their own set of design factors based on the types of exotic fibers that they specifically develop and use?

I will try to look into this more.

I spoke with Howard Wright, the Industrial Application Engineer for Samson Rope and he said the following:

"We’d suggest that you follow the TCIA BMP Crane Use manual and use a 5:1 design factor for calculating the WLL. One thing to keep in mind is that Amsteel and Tenex are made of two very different materials (dyneema and polyester) with very different physical properties. Polyester has 3 times the elongation as dyneema so remember to factor that in with regards to shock loading when you use Amsteel slings."
