Jim,
I've used the 250 Hz filter in my Corsair II, my OMNI's V / VI / VI+, and in
both of my Orions and so far I have never encountered any noticeable
ringing.
Having never worked a contest from California (or even the states, for that
matter), I can't judge your needs, but here in Europe the 250 Hz filter is
necessary. I found I needed it often in CQWW (CW) but rarely needed it in
CQ160 last week. The band I need it most on is 40m.
On December 26th when we had our annual "Christmas Contest" here in Germany,
with several hundred STRONG stations trying to work CW inside the lower 40
kHz of the 40m band, you were dead in the water without it! What waste of
money?
It was money well spent!

Our OWN personal preference is to use the wider
bandwidth filtering in a contest to find out who's out
there in a contest and then if a certain
station/contact is needed, then and only then would a
narrower FILTER be switched in. As far as the
extremely narrow 250hz filter is concerned using most
of our currently avaiable rigs the narrow filter
does'nt really provide any advantage because other
than being a waste of your hard-earned $$$ in alot of
cases using it causes a ringing/echo which can be very
irritating! BUT I must preface that statement by
saying that since I don't have the TT 250hz "Roofing
filter" (I have the 500hz) in MY Orion I can't say if
that actually occurs in our particular rig!!!
