In my experience it is quite rare that you get into the recording
situation where you can benefit from the different characteristics of
a omni or cardioid in a controlled way. Usually you never have that
control, unless you are recording the sounds from a nest, for
example, using a tripod and having plenty of time.
For the mono users, mostly film.makers, I have tried to simplify this
by having both a omni and a cardioid in the Twin Science housing.
Both capsules will be recorded into the separate stereo channels, so
you can select the best track at replay.

Raimund is correct about the freq. curve - see
The green curve is the cardioid, going higher.

The problem with a long cardioid is the wind and handling noise and
that it will stick out of the dish. It easily gets very unpractical.
Apart from all such questions, the field is wide open for
