[CAUT] New Scale / Scale Stick

[RicB]

Hi Folks.

I have a question to put to you all.  When one decides to change the 
string lengths as part of a rescaling endeavor, how does one account for 
the need to re-figure the striking point for the hammers ?  On the 
surface of it a very modest change in lengths would not seem to require 
much in the way of changing the strike line.... at least in the bass,  
but how exactly does one proceed ?

Thanks
