What about longevity - though a well processed fibre print will probably outlive an RC print, I cannot say that I have the time to really properly process the fibre prints. So in my case, I am sure my RC prints will last longer than my fiber prints...

When RC first hit the commerical market in the mid 70s I was still in the Air Force, we were told by both GAF and Kodak that an RC print will last 10 years in storage but just a couple of years if displayed. I have RC prints that are now over 30 years old, most appear to be stable, at least the prints made on Kodak paper, the GAF seem to be fading some. Fuji crystal archive color paper is rated for 75 years on display, so I dont know a black and white RC print will not last at least 75 years. I have read somewhere that an archival fiber print will last for 300 years but I dont know the science to back that statement.
