First of all I'd like to tip my hat as someone who rarely posts but loves to 
read all the messages here. Thanks to all for insightful and intelligent info, 
it is much appreciated even by those of us who don't frequently make ourselves 
known.

I have been making CS for a few years now using a simple homemade apparatus I 
learned about here way back when I started. It is three 9V alkaline batteries 
wired in series and terminating in a positive and negative alligator clip on 
each end. However I remember reading somewhere that the ideal voltage to use 
for such a simple setup would be 30V (mine being 27V with three 9V 
batteries)...first of all is this correct? Anyhow, I went to Rat Shack and got 
a two-AAA battery holder and wired it in series to make a total of 30V. I have 
made three batches of CS in this manner and find the reaction starts sooner 
than it did with 27V but other than that nothing seems different. Is it worth 
my while to keep using the 30V setup? If not, what is the ideal voltage I could 
utilize here? 

Thanks!
