Joe, I would experiment with both EPROMs and use the one that works best for 
you.  If you are satisfied with the sound of the transmitted CW tone, then I 
would leave it alone.  You may find that after critically listening to your 
rig and comparing it with others on the air, that in time, you will be able 
to quickly identify the Omnis.  Also, if you have access to the on-line QST 
product reviews, compare and contrast the keyed CW waveforms of the VI with 
that of the VI+.  The difference seen is caused by changes developed in the 
ALC circuit.

By my comments, some might think that I am down on the Omni VI/VI+.  To the 
contrary - I owned mine for thirteen years and it was the best and most 
enjoyable rig I had ever owned up until two years ago.  I simply decided to 
improve its keying and learned some things in the process.

In my opinion, TT reached the pinnacle of CW keying with the Omni VII.  I 
cannot imagine how it could be improved.  It is that good.
