[Elecraft] K3 Filter question - SSB

[Bruce Meier]

As I operate much more CW than SSB I need some advice and opinions from the
SSB contesters before adding additional filters for my K3s.  Currently I
only have the stock 2.7Khz filters in both K3s (main and sub rx) for SSB.  I
have 400hz and 250hz for CW.  If I wanted to add an additional roofing
filter for SSB contesting, would I add a 1.8Khz or would I add the 2.1Khz.
