I would agree with all of that, except for the last point. When faced
with S9+20dB  QRM in a contest, the ability to decode weaker stations is
at the very -top- of my list. The  strong stations will already be in
the log, but the weak ones are much more likely to be valuable
multipliers. We all try to use the wider filter when we can, but sniping
rare and distant multipliers through a wall of QRM is where the narrower
(sub-300Hz) filter can sometimes score.

You will - looking forward to it already!
