Personally, I follow the K3ZO school of filtering.  I prefer using my
neuronal network for filtering, especially when running in a contest.  As my
operation is mostly CW, I have the stock SSB, the 1 kHz, and 400 Hz filters. 
I find myself using 1 kHz most of the time and have always done it this way,
going back to my Drake R4B days.  I suspect Wayne got a better deal on his
filter options than I did :.)
