Everyone's ears are different, but I used a DSP passband of 1.1 KHz for most of the 2,200 QSOs I made in the 2009 CQ WPX SSB contest (roofing filter was 8-pole 1.5 KHz). I don't remember how far I had to shift the center frequency, but I think it was down to about 0.85 or 0.90 KHz. It definitely helped, but if the splatter is inside your passband (and unfortunately much of it is) nothing will make a significant difference other than maybe taking the time to tell the guy above or below you that he has a dirty signal (which I did twice) and hope that he backs off the gain or compression (which happened once).
