Unless you live in an exceptionally high humidity area I don't believe the
rod under the keybed is particularly useful.

I would prefer to use a 50 "belly bar" (as above) and then a 35 watt under
the "long beam" and a 25 watt rod under the "short beam"

I always hang under the beams (mostly until I choke)

I try to find a location that will be equidistant from the humdifier and the
nearest rod.

I don't know if I qualify as an expert but I can tell you that since I
started placing rods under beams instead of "under the sound board" the
stability of the tuning has improved--especially in the tenor which tended
to get out of hand. My climate variation here is 4% to 84%.
