Both threads have been merged into a single V-P thread. The V-P forum isn't as slow as you think. Having less traffic doesn't make it slow, especially since new threads get responses just as fast as any other section.
Please do not start multiple threads on the same subject. First, it's confusing to members trying to help you. Second, it's confusing to Mods to get things straight so you get the most effective answers or help from members for your problem.
Third, You might as well bite the bullet and change both cables while your in there. Lubing seldom works, whereas new cables always do the trick.
