                   This thread is  good food for thought. I for one consider 
letoff an essential part of the equation( so does every one else) that should 
be added to the list below in the no. 4 spot.
     One thing I'd like to add is that I set very close let-offs. May be 
closer than many factory specs because pianist like tonal control and power. 
I learned this from Norm Neblett years ago. How close? 2mm in the bass ,1.5 
tenor and 1 in the trebles. My blow is usually 1 3/4" in stwys. If I was 
setting wider let-offs in the bass couldn't I theoretically set the dip 
shallower?as escapement is happening sooner and deeper in the treble cause 
it's happening later.
   Hmm Maybe I'm just getting tired. Later
