Peter at Doublehelixcables.com sells some very good stranded UPOCC copper wire in both clear and translucent black polyethylene (cryo treated as well). He has had it available to DIY'ers for several years now and gets it custom made from one of the few official producers of OCC wire. I use it almost exclusively due to the quality and price (and Peter's great service and advice).
As for Navships SPC, I usually sleeve cables to reduce movement-generated cable noise.
I am happy that more companies are making high quality wire available for DIY'ers. When I first started up and before Peter had his own wire, ALO and Cryo-parts (now closed) were the only places to get it and they are expensive as chip.
