 information no matter what (after all, any scan is essentially a digital

 too much data - and for rare docs you might only get the chance to scan
 them once. For rare items I'd rather have maximum quality "just in
 case", even if it does mean more storage space. 
Exactly.  Storage is incredibly cheap these days.  It's easy to throw
disk space at a problem.
If you had to fit all the scans onto RL02 packs, I'd see your problem...
