RC, My opinion is that at first the filters narrower than 400Hz would be too much for you at the early stage of seriously working CW. Later you could add narrower filters if you thought needed them. It all depends on what YOU want to do with CW.
When I was a novice in 1976 I used a Heathkit 400Hz filter for CW, which was the only mode we were allowed to use. It made working CW much more pleasant, because the Novice portion of the bands were very crowded back then. I now use the 5 pole 250Hz filter for almost all of my CW operation. I have had both the 200Hz 8 pole filter and the 5 pole 250Hz filter, and in my opinion the 5 pole 250Hz is the better of the two. I also have the 8 pole 2.8, 8 pole 1000 and 8 pole 400Hz filters in both the main and sub RX's. The RX also has the 5 pole 250Hz filter. However if I were to load up with filters again I would only have a 400Hz 8 pole in the sub RX for CW. The 250Hz filter is too narrow when working split, because I want to be able to hear more spectrum on the frequency where the DX is QSX. I sometimes use the 1000Hz filter in the sub when working split also. 73, Tom Amateur Radio Operator N5GE ARRL Lifetime Member QCWA Lifetime Member "Farmers have learned that rotating crops improves productivity and saves the land.
