Have a 2007 Silvia with PID, paired with a Rocky Grinder of the same year both went into service in 2008. Wondering how much of an improvement in shots could potentially see from a grinder upgrade or should I just replace the burrs? Not really too fussed about the steps on the Rocky as normally just adjust the volume slightly and by doing so are always able to hit desired shot time and volume. Wanting to get the most out of the Silvia and improve shot quality further.
