I bought Sachs New Success brifters and derailleurs when they first came out many years ago. The design was licensed from Campagnolo but used Shimano cog spacing. I don't know who actually manufactured them, Sachs or Campy. They were on my primary bike for a long time and have since been transferred to my cyclocross bike. They haven't given me a bit of trouble. I can't comment on your components but the brand has put out some great stuff.
