Other option to reduced wear and tear is the Jagwire Elite Sealed Shift Kits, which allow the entire cable to be sleeved right to the derailleur.

How do they work with the existing cable stops? Do you drill them out or clip it / zip-tie it around them?
You don't need to drill them or anything, just fit them.
