In two minds about the Gore-Tex cables. They are not better than a good conventional cable but they stay cleaner and for that reason keep working well for longer. But cables are not one of my problems. Bike cleaning for me does involve releasing the outers and washing through with WD and lubricating with "Dry" chain lube. Never have a problem with the cables except that I do seem to get gear cable inners breaking a thread. Normally every couple of years and I change the inners but always use Stainless steel inners.
