Pro Set with HC4 element for SSB contesting.  I have changed KSB2 part
R14 to 4.7K (it was the largest value less than 10K that was in stock at
the local Radio Shack when I visited the store).  In my recent ARRL 10
Meter Contest effort, I noted a lack of "punch" in breaking pileups and
maintaining the VOX between syllables.  I plan to increase the value of
R14 to 5.6K or more."

This is the only mod I've done to my KSB2.  I had to increase the value
of R14 to 6.8k (originally was 1k) in order to trip the VOX and get any
ALC action.  I now have adequate audio from my Heil HC4 element to trip
and maintain the VOX and get one bar of ALC.  Because I consistently get
unsolicited reports of outstanding audio, I don't care to try any of the
other KSB2 mods.
