They seem to recommend unbuffered paper for all but silver gelatin 
prints.  The Renaissance is unbuffered, the Apollo buffered.  Both come 
in "paper" and "tissue."  Although it is a little heavier, I use the 
(Renaissance) paper because it is easier to handle than the tissue.  
These papers now also come in 13 x 19.  The buffering issue is 
something that could use clarification, but since the papers I use are 
acid free, I thought the unbuffered a safer bet.
