Compliance yes... but will the higher ratio yield higher hammer velocity for
same hammer weight ? At what hammer weight (given action parts materials) will
compliance become such an issue that it defeats any increase in action ratio ?

And doesnt the stored energy in compliance flex have to be released some how
regardless... doesnt some of this end up coming out on the hammer / string
impact end of the <<equation>> ?

Then... action saturation.... when is too early ?? or is there such a thing as
too early  or too late saturation ?...
