I had replaced the newer 3.27 with the older 3.25 as the SSB NR didn't please 
me as much. But after examining your .doc file with settings I tried the 3.27 
once again using the AGC settings in the .doc file. After changing a few 
settings the SSB was very nice and CW also seems to work fine. Here is what I 
did:

First my RX equalization is: #1=0, #2=1, #3=1, #4=-1, #5=-3, #6=0, #7=0, #8=0

AGC HLD=0.15, AGC PLS=nor, AGC SLP=05, AGC THR=5, AGC-S=20

The setting changed from the .doc file was AGC SLP=05, from your 00, which 
didn't surpress enough some of the huge static crashes we were having.

Then I found the SSB setting most effective to me was F4-1 and F4-2. They 
didn't exhibit the hollow/echo sound of F1- or F2- settings which I felt 
reduced the clarity of the SSB in noisy conditions. I use AFX a lot, but the 
same experience with it on or off.

I am cw about 80% of time so experimented with it and had very pleasant 
results also. But following suggestions of more experienced users on this 
email group, I've found that AGC off and using AF about 50% and then using RF 
to control signal volume/intensity works much better in noisy conditions for 
me.

The essence, then, is to try F4-1 and F4-2 with the new 3.27 to see how it may 
work for you if you use SSB mode. I'm continuing to experiment with different 
settings in various conditions as the type of noise effects what needs to be 
done to surpress it but enhance the signal.
