There are some issues with flange replacement. New flanges are going to 
get loose at some point down the line and need retightening. You can run 
into difficulty reinstalling flange screws into an aluminum rail. If the 
strike points are grooved, you will need to file the hammers. If you 
should get a batch of not-so-well-made flanges, travelling could get 
into some time. And if you need parts from Yamaha for a gray-market...

By replacing the cords, I've gotten a perfect job every time. Working 
quickly, I can count on it taking 2 hours. It's a good, reliable repair. 
If there is some question about the condition of the flanges or, of 
course, if the action doesn't have butt plates, then I replace flanges.
