Last week I sold my 500 Hz filter, and ordered a 250 from Elecraft. On Friday night, the new filter hadn't arrived yet, so I operated in the CW DX Contest with only the 2.7K filter. It worked great! I couldn't see any difference between the 2.7K and the old 500. The skirts of the DSP (set at 300 BW) dominate over the filter skirts, and I never had one case of desensing or overload. On Saturday afternoon, the mailman delivered the new 250, and I installed it immediately and operated the rest of the contest with it. Once again, I couldn't see any difference. The radio sounded exactly like it did with the 2.7K and the 500.
If you frequently feel the need to crank your DSP width way down below 300 Hz, you may benefit from the 200 filter, but I don't do that and don't plan to buy the narrow filter.

There was some big DX contest this weekend. I played in it for about 30 minutes with my K3 and my bugs. Fun. By the end of my time on the air, my "small want" for a 200 Hz filter had been upgraded to "the next thing I buy".
