Inserting/extracting the board into/from the double sided "sandwich" is 
where 90% of wear and tear occurs IMO. Epson dye ink on Epson 
transparencies handles this best IMO. I wouldn't even think of using 
Ultrachrome ink double sided artwork more than once unless there is a 
clear overcoat. Single sided shouldn't be a problem with any reasonable 
combo.
