I was curious and looked up the Vectran sheet.

And compared it to the Dynex Dux sheet

One comparison I got (apples to apples) was for 11mm rope size. The other sizes are
1mm diferent.
So....11mm shows
Vectran......#21,000
Dynex Dux....#37,000
There are many other comparisons, and other factors. But the way to think of synthetic rigging is not just how strong do I need to hold the rig up, but how strong do I need to stop creep? By keeping the static load below 20% of breaking strength you will end up with next to no creep. The charts for this are at:

You can see the potential to have less creep than SS wire!
I used mostly 7mm for my 34' Searunner Trimaran. Cutter rig double spreader. The original specs were for 7/32" and 1/4" wires. We can really put a load on the rig with the stability we carry.
So far so GREAT!
As a little aside, I was talking to Hampidjan guys a while back about all this, he told me they are more interested in big boat stuff. They were producing 3" Dynex Dux with a double overbraid for an oil rig!.....It is "off the charts" I see 2" or 51mm has a breaking strength of 242 TONS!
Kee-rumba!....:-)
