[Elecraft] K3 Audio routing question

I've been following this discussion (at least the parts that aren't
super-technical) since I recently installed the sub RX and plan to use it
for CW contesting.

As a new sub RX user I may not understand all the ins and outs of it, but
here was my plan.

When running, I like to use Split with the xmit freq on VFO B.  I then tune
the calling stations, if required, using VFO A.  I normally use a fairly
wide BW (300-500 Hz) to avoid much tuning on strong signals.  I was hoping
to use the "diversity" mode for this so that I could monitor two antennas at
once, one in each ear.  If copy became difficult or if the other antenna was
creating more interference than help, it would be useful to use the
"balance" control to focus my attention on the signal I was trying to copy.
I understand this is not true diversity, at least in the extreme.  But it
does seem useful, at least to my simple-minded way of looking at things.

I'm starting to prepare for the IARU contest this weekend, so if any of you
more experienced sub-RX users have any suggestions please share them.
