[Elecraft] CW filter settings. What are yours?

I have mine at OP1 (SSB), 1.0, 0.4 and 0.1. The narrow one has only been
possible for me since I replaced the crystal in my K2 # 2198, before
that the attenuation was too large. The setting I use the most is 1.0,
the SSB-bandwidth I find too noisy and the other ones I mainly use for
zooming on to a weak signal or one which is subject to interference.

Yes, the K2's processor has to get a new frequency measurement for each
setting. Otherwise it won't know how to equalize the pitch as you switch
through the four filter settings.
