I was adjusting my Lehman and got wondering about something. 

How should the boom be set? Should it be level or should it have a
slight downward drop at the at the mass end. 

If there were a drop at the mass then it would seem that re-adjustments
would be less frequent. And as the movement of the base is what
produces the wave forms then it would seem that as long as the boom
did not touch any of the sensing/supporting hardware then there should
not be difference in it's performance.

Any comments from anyone?
