I still think there's some confusion here.   The issue isn't whether  
to use an acidic board or to use a non-acidic board; you wouldn't  
want to use an acidic board under any circumstances.  The issue is  
whether to use (1) a pH neutral, 100% rag museum board (non- 
buffered), or whether to use (2) a buffered board where the pH is  
raised to 8 or even 9, to counteract the tendency for the print to  
become  more acidic over time.
