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.
