Jon,

For purposes of instruction, any configuration would be fine - as 
long as you have naturals to both sides of all sharps, and the 
geometry is such that they can be regulated with more-or-less common 
specifications. For purposes of demonstrating principles of action 
function and regulation - the less, the better. So a 3-note action 
model (2 naturals, 1 sharp) is very useful. For purposes of 
practicing fluency and evenness of regulation, more notes are useful 
- so perhaps a C-B or F-E configuration would be useful there, so 
that all possible groupings of sharps vs. naturals are included. And 
since you are more-or-less pioneering here - why not make several 
different configurations (depending on how many extra brackets you 
have) and see which prove most useful? I can think of a few classes 
that could use a multi-note grand action model, so please let me know 
when you have a few assembled.
