Digital BW, The Print

One of the Ilford Pearl papers has a terribly short life span while
the other two are quite good can anyone tell me which is which. After
buying the wrong one you think I should know but it's all long gone
and so's the box it came in. Now looking at them I can't be sure which
is which.

I just know the one I bought the prints didn't last a year before they
were total green crap while a couple of other papers still look great.

Thanks

PS I will be using this paper with both UT-2 in a 890 and a i960 for
color with Canon ink.
