set letoff to get acceptable aftertouch?

[Barbara Richmond]

Daniel,

Like Terry said, decrease hammer blow distance.  Then your problems 
(bobbling hammers/heavy touch) are probably due to too-strong hammer and/or 
damper springs...and it also could be too-soon damper lift.  Also checking 
the height of the balance hole with a balance hole reamer would be in order. 
OK, check for too-tight balance holes and bushings, too.
