   The "feel" of aftertouch might be increased by increasing the amount of 
work that goes into it, but if you are feeling the hammer dropping after 
let-off, understand that that is not what you feel in playing, (where the 
hammer is rebounding into the back-check). 
    If the checking is dependant on the amount of drop,  you have something 
terribly askew in your hammertail/backcheck organization.  
    Setting the springs higher than what it takes to lift the hammers as fast 
as possible without feeling the recoil will gain you virtually nothing in 
repetition speed,(unless there is something else wrong that excessive spring 
is making up for). 
   The amount of drop is the amount of resistance the pianist will have to 
work through to achieve escapement.  The greater it is, the more of the 
keystroke's last bit of control must be done under spring pressure, and this 
has an effect on how controllable let-off is.
