The plot thickens. I came across this product page at RobLine an Austrian rope maker and they have a bunch of lines for mooring, docking, that will be good for anchor snubbers.
Interesting quote from that page:
Robline caters to the trend toward using different fibers for mooring and anchor lines, depending on the specific use, and introduces cordage made of polyamide (known as nylon) in order to utilize the high elasticity of this fiber to cope with critical shock loads.
These lines are available from upffront.com, in Germany, who ship everywhere, among others.
