As I mentioned, gear noise was one threat that kept me from making the move sooner. Well, most people will tell you to go with FRPP gears if you want them quiet, and that's just what I did. I opted for the ever-popular 3.73 ratio (PN M-4209-F373N; MSRP $ $179.95). This set now benefits from a new Face Hob Process, which is said to deliver higher quality, strong gears. Combined with Dave's expert installation, mine are indeed library quiet.
