I realized that I hadn't posted the results of the 620 rebuild here- as this was the bike that the initial cable issue was about.
I ended up using the titanium braided shift housing and grey brake housing:
The titanium and the grey kind of compliment each other, as the titanium is under the bars to the downtube and the grey is above the bars.
The brake housing I couldn't use was sent to a C&Ver who had a use for it.
