Since I work mostly CW, and am not too interested in diversity
reception (don't have the antennas either), I was thinking of the following:
Main Rx: 2.8 - 1.8 - 1 - 400 - 200
Sub Rx: 13 - 6 - 2.8 - 2.1 - 1 or 400
I know that's a lot of filters, but other than going broke
Wow, that's over $1200 on filters alone! You haven't said much about how you plan to operate (other than mostly CW), but 6 of your 10 filters are for voice modes (i.e. all above 1.0 kHz). Are you sure you wouldn't rather use that $750 for something more aligned with your main interest?
Just to complicate your choices even more, Inrad has 2 additional filters besides what can be ordered from Elecraft:
http://www.inrad.net/product.php?productid=299&cat=140&page=1
http://www.inrad.net/product.php?productid=316&cat=140&page=1
It may also benefit you to order your filters directly from Inrad rather than Elecraft since they offer quantity discounts (up to 20% for 10 filters...see page 16 of their catalog). That could save you about $120 but perhaps you're ordering your unit assembled.
73, Bill
P.S. Don't forget Elecraft will *someday* offer variable bandwidth filters!
