Rise time alone doesn't determine the degree of 
clicking. The best envelope shape for CW is one that 
has no sharp corners.  An exponential curve always 
starts with a sharp corner so will not yield least 
bandwidth.

I recently upgraded upgraded from the INRAD mod to the 
W8JI  mod on my MkV. It provided another factor of 
two decrease in bandwidth as determined by listening 
on another rig (with the input attenuated and the AGC 
switched off to preclude receiver artifacts from 
affecting the measurement).

Most notable was the decrease in the first click, 
which was significantly more prominent with the INRAD 
mod.

I'm happy with the result but I see it as somewhat of 
a lost cause.  Virtually all rigs click (my MkV is 
now, by far, the least clicky of the rigs I have) and  
I'd be really surprised if more than 1% of MPs ever 
get the mod.
