Fixed it for you!Spectra/Dyneema are a polyehthylene and they are NOT EXACTLY the same.
Dyneema comes in 3 grades - SK75 / SK78 / SK90 (plus older versions as SK60 / SK62 / SK65)
Interesting (older) article: http://www.sailing.d...SK78-Part-1.pdf and http://www.sailing.d...SK78-Part-2.pdf
or check Seahorse jan'10 issue page 42 on SK90
