There are some really good QRQ ops out there.  W4BQF and W2UP come to mind.
I know that W4BQF routinely copies and sends over 100WPM, and he uses an
Icom 7700.  Having owned the '7700, its QSK is very fast -- until you add an
external amp where keying artifacts begin appearing on anything but the
fastest switching amps. The '7800 I owned did not have this problem, nor
does the K3.

I agree that getting the K3 to run more accurately when using faster CW and
an external keyer would be a welcome update -- but not at the expense of
introducing any other artifacts (e.g., clicks, delayed T/R time, etc.)
