Kentobin,
So far the only furler that fits a Dux forestay is Spintec. There is a conflict with the size of the rope and splice not fitting a foil designed for wire. The splice on 9mm Dynex Dux has a two foot bury. This makes the rope fat at the top and bottom.
A number of boats have left the wire on the forstay (the Westsail for one) There is no problem swapping out or mix and matching Wire/Rope.
It is recommended if you change one side, change the other side to match.
Continuous line furlers have replaced Roller Furlers on many boats now also. Photos at:

There is a lot of discussion on SSB's. Dux has the same insulator properties as phenolic. You can run a bare copper wire up the side of a backstay for a radio. We thought maybe to run it up inside the rope, but this will create a stress riser according to the engineers.I am no expert, but we use the bare copper wire in Alaska on the big boats. Works great.
What size boat/Rig do you have?
