[Elecraft] Heil Proset question

[Ken Alexander]

Hi All,

Just ordered a K2 last week and am looking forward to
melting some solder and having some fun!

I see that Elecraft offers a Heil Proset tailored to
the K2.  Ironically, I bought a Proset just a few
months ago with the HC4 element.

Can anyone tell me how superior the mic in the
Elecraft Proset is to the HC4 element in the set I
currently own?  (I'm really hoping someone will tell
me I can keep the set I have, but an objective opinion
would always be preferred!)  8-)

Thanks and 73,

Ken Alexander
