  Paul,

I suggest you compare your keying waveshape to that shown in the K2 
Keying Waveshape Mod instructions.  If yours is considerably different, 
then you have a hardware problem.

Fortunately a somewhat higher weight sounds better than a somewhat low weight, so maybe thats the reason why there is not much discussion about K2 internal keyer. But for higher speeds a correct weight is important. For my taste the keyer is not acceptable and I soon gave up using it entirely.

A lot of the answer depends on the particular operator's experience and how he likes to listen to CW at higher speeds.
