I had good experience with the Jagwires. I recall LBS mechanic being very impressed by DA shift cable and housing. If your current cables have gotten junky, either one will be a great improvement, and I doubt the difference between them warrants a big delay in replacing them. Either way, be sure you work in a clean setting to avoid getting grit on the cable or housing during installation; make good cuts with a proper tool, and measure twice.
Good luck
