However, Rob recommended a change in the CW signal rise time to no less than 6 milliseconds - I forget which menu item it was - but he criticized Icom specifically for a default setting that induced key clicks.

ICOM rigs are NOT among the cleaner ones -- that spot falls to Kenwood, 
which is second to Elecraft (and, I suspect, Flex 6000 series, which I 
haven't measured).

Yes, adjustable rise time is a REALLY bad idea, which K6XX pointed out 
in 2013, and which I measured on the air for K6XX's talk, in a 
neighbor's ICOM rig. Slower is better, but Elecraft's is best by far, 
carefully shaped keying waveform.
