The Nikons have a reputation that the true optical resolution is close 
to the manufacturer's specs on sampling, a Nikon 8000 sampling at 4000 
SPI will deliver around 3700 PPI optical resolution . So if you like to 
have as much information as possible in your scan and never redo the 
scan  then use the 4000 SPI setting and use the 16 bit output. For 
archiving a normal Tiff file at 16 bit can be smaller than a compressed 
16 bit Tiff file. Compressed PNG will deliver a smaller file but that 
format is less supported. Then there is the "RAW" output of Vuescan or 
the DNG format.
