Okay, so what you are saying is that most tuning pins don't turn on their own under the pull of the string tension, but that somehow they lack the "real stability of tuning"? IMHO, either the pin turns on it's own or it doesn't. How does your experience differ? FWIW, yes, some tuning pins have less torque than I would like, but that doesn't mean that they spin on their own.....
