Hi Marchal
I have tried resistive damping but with limited success.  I am currently 
using copper plate damping with a 1/4x4"x2" copper plate on my Lehman with a 
magnet on each side of the plate.  This arrangement has thus far proven to be 
the easiest for me in obtaining adjustments, etc.  However, I do plan to 
experiment with resistive damping in the future.
Lots of luck in your efforts - Let us know which method worked for you.
