[K3S] sub receiver filter recommendation

[Elecraft mailing list]

I am migrating my K3 [Ser# 6232] to a K3S with a sub-receiver. In the
K3S main receiver I will have the following crystal filters from the K3:

2.8Kc 8-pole Elecraft
1.9kc ?-pole Elecraft
0.5kc 8-pole Inrad
0.2kc 5-pole Elecraft

I operate almost exclusively CW in contests and DX chasing. in contests,
I anticipate using the sub-receiver in a SO2V arrangement, the main
receiver in S&P and the sub- in running. Given this operating
arrangement, which single crystal filter in the sub- would be "best?" I
understand that personal preferences play a big part in choosing a
filter, yet I'm wondering if there's a broad consensus in the filter
width that most folks choose, most of the time, in this application.
Thanks in advance for any and all opinions and advice.

Thanks to all respondents. To clear up one point... "Migration," as per
Elecraft, means to transfer whatever components in a K3 that will work
to a K3S. In my case, just filters. I end up with a new K3S and the
original K3, ie two radios. I have never operated SO2V in a contest. So,
my curiosity is focused on which CW filter in the sub-receiver, if any,
works best in the SO2V contest environment. With the K3, I have usually
run with the 500cps filter, so I'm guessing there should be no
significant difference when operating SO2V. But, I want(ed) to get a
feel for this mode from others who have used it in contests. The
Elecraft 400cps filter seems to be slightly preferable to the 500cps
filter for reasons cited. Diversity is not an option here [limited
antennas]. Again thanks.
