[CQ-Contest] CW filter ideas for the MP Field

[KI9A@aol.com]

Gang, 
I have a new MP Field, with the INRAD roofing filter, & the factory  500hz 
filter. I want to add another CW filter from INRAD, & am torn between  cascading 
another 500hz (or the 400hz) filter, or just adding a 250 hz  filter.  I'd do 
both, but, am adding a SSB filter already. 
 
Also, whats better, adding them in the 2nd or 3rd IF? 
 
Thanks in advance!
