Deadeyes vs just lanyards with HM materials

[Jack]

Yes that is the article I failed to post Bott.

As far as your question goes, If I understand you, you wonder if you can make off the lashings in the traditional manner, on top the Dead Eye?. I would say "sure why knot?" I would not worry about chaff if I understand what you are talking about. Dynex is used for butchers gloves because the material is so chaff resistant.
I would question using a different lashing material though. If you get most anything else you will have stretch and creep to deal with. After using Dux on the shrouds, you have the makings of a very strong no creep no stretch set up. If you lash it with with something else you may loose all the advantages of the Dux (except weight saving)
Also a traditional lashing hitch may not work with Dynex as it is very slippery. We have found multiple hitches or turns are required with Dynex where you could use much less with a poly or nylon line.
