Actually, I switched to this method too, mainly because of QRQ mode. And
I got a 400 Hz filter for the main rx.

You can mitigate that problem somewhat by listening to the DX on the
wide sub and the pileup with the narrow main rx. If the split is
(roughly) larger than the filter bandwidth difference, then loud,
continuous callers in the pile don't bother the DX signal, only your
ability to locate the weak caller in the strong pile. That being said, I
put a narrow filter in both receivers.
The unconventional technique of listening to the DX on the sub and the
pileup on the main has another benefit - you don't have to use SPLIT
mode which degrades keying at high speed and disables QRQ mode. It took
me a while to get used to it after decades of doing it the other way,
but I think the benefits outweigh the change in my cage.

My K3 was originally set up this way, 400 Hz in the main and 2.8 kHz
in the sub.
When working DX pileups with the main on the DX and the sub on the
pileup, I definitely noticed the 'pumping' effect on the sub only.
It was sometimes annoying when the DX was working a weak caller and
the usual loud idiots were continuing to call.
