This seems like an increasingly commercial trend cluttering up this list, with
dubious claims to boot.
I guess that I'm not a "savvy operator" since I use the discredited 400 Hz
filter and manage to get by.
Apparently, 700 Hz is a magical bandwidth, just as 43 feet is a magical length
for a vertical antenna.
Who knew?

Unless you have a panadapter, you'll never work weak stations, if you can't
hear them because they're outside your passband! (This is the beauty of 700
Hz!) In fact, many seasoned Elecraft K3 owners feel that using the radio's
400 Hz default (NORM) CW passband setting, is kind of like "viewing the
world thru a drinking straw while riding a bicycle". That is, it would be
fairly easy to skip right past a weak calling station, without ever
realizing it was there.
But even more importantly, prolonged scanning with a 400 Hz passband can be
tedious and fatiguing. This is why, band conditions permitting, savvy
operators prefer a 700 Hz passband:
o "for general CW tuning" -- W3FPR
o "for scanning the band (or a pileup)." -- K8GU
o "for combing through the pileups with VFO [B]" -- NI0C
o "to cruise the CW bands from a wider perspective" -- N1LQ
