Hi Ed, I don't use Renner anymore. The graphite in the bushings attracts moisture and around here it's hard to avoid it. Plus the shanks twist more than Abels or Tokiwas and after a year or two, I have to pull off a dozen or more to reset straight because they're tipped beyond burning-in. Only a few with Abel or Tokiwa. I had to repin the top flanges on a new backaction and the jacks on a customer's piano. That hurts the bottom line. Jon
