Sorry to do this to you guys but .....

I need some roofing filter advice:)

Currently I only have the stock 2.7K filter and it has worked fine for casual rag chewing and some dx'ing.
I've been operating my K3 for over a year and it seems I don't have any strong signals near me creating problems.

Over time my interests have changed and now I'm pursuing primarily cw dx'ing on 160 and 80 (lots of weak signals).

I'm attempting to fill out my 'elecraft cart' to purchase the second receiver and am stuck on the filter choices.

I can't afford lots of roofing filters so I'm thinking of going with one cw filter on both main and sub (for diversity receive capability).

It seems the 250 or 200 may be too limited in application so given the above would you suggest the 400 Hz 8 pole or the matching 500 Hz 5 pole filters?

thanks for any advice.
