Any question answered...

So, if I'm right, I can just buy some campag cabling and run it with outers all the way from the shifters to the derailleurs. Or do I not actually need campag cables? I'm a little green when indexed gears and cabling are involved, ie. never before.

My favourite option so far is to find some clamp on cable stops, but I've had no luck finding them in silver, which is a must really.

You dont need Campag cables. But you do need campag compatible ones.
