Jim, I see a lot of new pianos with coils higher on one side of the pin than the other which when tapped down the pitch drops dramatically. New Samick grands in particular seem to suffer from this.(not a put-down folks-just an observation-flame suit is ready :-) I do not get in the habit of tapping them down as this would create a floor tuning nightmare. But when I restring or loosen a set of dead bass strings to "liven" up I always use a stringing hook to pull the coils tight and after pulling up to pitch tap them down with the impact coil tightener. Then I pull them up to pitch again and it is amazing how stable they are after that. In this case I also tap the bass string loops down to the plate.
