I too am CW only, have had a K2 for years, and when I went for the K3, went through the usual "which filter" questions.
I come from a 250/500 Hz background (mostly Ten-Tecs). I opted for 200 and 400 Hz along with the stock 2.7 kHz. My thinking was that I wanted each filter to have, more or less, a dedicated purpose, in the interest of simplicity. 2.7k: tuning around, casual listening, not engaged in QSO, not listening to a specific QSO 400: listening to a specific QSO or engaged in one 200: engaged in a QSO and interference occurs or I need to pull weak signal out I was pretty certain that 400 was something I wanted, so the real problem was whether to get 200 or 250. I opted for 200 because 250 seemed "too close" and I figured that if you need to kick in the 200, you really NEED narrow. I have zero regrets about the setup and will likely never consider another for my style of CW ops. Nice knowing it's done and I can focus on the QSOs instead of the filter choices. My only concern about the 200 was that it's so narrow that I might hear ringing or some other undesirable characteristics. I find this to be 100%, without a doubt, false. The 200 on the K3 performs better than any 250 I've tried on other rigs (admittedly, all Ten-Tecs plus an IC-706MkIIG) My 2 cents. --Andrew, NV1B ..
