Well, I switched to the linked housing from the cheap TRLREQ brand and it is the same for brake and shift cables and superior, mostly vastly, in other ways. Actuation is more precise, tight turns are possible, no housing ends are needed, the links are reusable and color combinations can be used to mark individual cable runs.
