assist springs

[David C. Stanwood]

Dear Richard,

If for no other reason, using a spring that works 12 grams or so means the
absence of two large key leads in the middle of the key.  When combined
with a proper match of hammer weight and ratio this means that only a small
amount of key lead is needed... I like that...  The absence of lead that
comes with using wippen support springs has consistently shown to improve
repetition by lowering key mass.  The adjustability feature is not used
that often but when it is it's very easy with the adjustable spring and if
the need arises one doesn't shy away from the task.  Without the screw
adjustable feature one will find excuses to put off the task of fine tuning
the touchweight.

PS - Strike Weight Ratio is SWR for short...
