I received my 2 boxes of the TT Baryt Vario fibre paper on Friday. Today I've tried it out.
It's supposed to be Agfa MCC so I entered the details of MCC into my RH Designs Analyser Pro, put in a neg which has been causing me loads of grief lately, worked out the exposure using the Analyser Pro and exposed a sheet. Exposure was spot on!

A far better print than I've been able to make for the last couple of weeks. No blotches, fogging or other signs of ageing. Really pleased.
I've just ordered another 4 boxes and the wife's going to clear out the freezer and make room for them. I've never used Agfa paper before, I can now see why many people loved it.
Cheers
Mike
