Now that we are talking about ppp levels, I see your point. But I am not sure I
have such strong whip rep spring strength that this is a problem. Besides... at
really low levels of  play the hammer doesnt need to check, it just mustnt do a
double take on the string.

I see your point. Never thought of this actually and am glad for the thought.

Sorry.. the repetition lever spring. I dont ever have this stronger then allows
for a slight feel in the key. This isnt very much tension in relation to the
checking problem we are discussing.
