My very slight issue with the RS dropouts is a philosophical/ethical one. Much like Cinelli, RS is both a man and a brand who also makes frame parts. I would never want my (undoubtedly inferior) work to be ever mistaken for the real deal, just as there are people who post "Is this a real Cinelli" in the C&V forums because a builder used a Cinelli-stamped shell or crown. If I do go with RS dropouts, I would probably fill the lettering with silver and file it smooth.
Weird, I know, but it is what it is, and I am what I am.
