[Elecraft] What crystal filter do you use the most?

[dw]

Hello gang,
Just ordered my first K3.
I haven't ordered any filters or accessories yet.
Want to wait and see what I really will need.

I'd like to illicit your experience with the use of crystal filters for
CW.
What filter do you find you use the most and why?
I won't be using the K3 for contesting....just casual CW-only DXing and
occasional rag-chews.
Of late, I've really enjoyed getting on 40m and 30m at sunrise.

Many thanks in advance
N1BBR :-]
