Digital BW, The Print

I've been doing a lot of research through the archives on paper
yet still have a couple questions. Inkjet Art makes some pretty big 
claims about its Museum Digital Art Paper saying it's the same 
formulation as PFA Hot Press and that it can handle big ink 
loads "reaching unheard of maximum densities"! Wow, sounds
too good to be true, has anyone else experienced the splendor of 
these "unheard of maximum densities" with this paper?

Does anyone have experience with the above version or the original 
205g/m2 PFA Hot Press paper to know if it is heavy enough to 
withstand buckling? I'm also wondering if it gets the mottled-
burnished look that some papers can get in the dark values from the 
ink load. I understand that it doesn't flake.

My samples of H PhotoRag flaked like crazy even after brushing and 
blowing, no buckling or mottling though.

I'll be ordering some sample packs to do my own research but I've 
got a deadline (don't we all) and PFA Hot Press or its clone from 
Inkjet Art seems like a safe bet for now. 

Thanks,
Jim
