I think if an SSB signal is so close to you that it is pumping your agc through the 2.7 filter, the frequency is hopelessly splattered anyway, and you'd best be moving on.  I did narrow the DSP down by using HI CUT, and usually ran it at LOW=0.15 and HIGH=2.25.

I’ll echo this experience. I find the DSP filters to be stupendous. All I have for SSB roofing filter is the stock 2.7 kHz 5-pole filter. The heavy lifting is done in the DSP.
