[Elecraft] start with straight key or paddles?

True, mode B did catch on (long before 1979) and circuits and chips were purposely designed to implement it.  But the evil that spawned mode B occurred in an improperly designed keyer from the mid-1960s.  Somewhere I've specific details...but not with me now.

Which is the **only** "advantage" that can be claimed for mode B, though I see no value to this "advantage" and a "lot" sooner is not how I would quantify it.  If mode B reduced the number of paddle manipulations required over mode A, it would have purpose.  But exactly the same amount of paddle manipulation is required regardless of character sent.

There's 100 percent agreement here!  Learn one mode and the other will seem impossible.  

I haven't any moral objections to mode B, just to the firmware designers who design an embedded keyer in a rig to use only one mode and that mode is mode B!  (Example...the nasty FT-817!!)  For whatever reasons some such firmware designers seem more often to choose mode B, so I actually recommend that mode B be the mode learned if one is just learning iambic keying.

Thank goodness the Elecraft keyers allow either mode!
