Digital BW, The Print

I have done a search here for this paper but didn't turn up anything. I 
would love to hear from people who are familiar with it.
I have been using Premier Fine Art 270 gsm with success but sometimes I 
don't want the cream/vanilla color. I am looking for a White paper that 
is Smooth Matte and acid/lignin free. I found out about Dual Matte 
210g...12mil C2S and it's very Inexpensive. Apparently it's made from 
wood pulp instead of cotton therefore the price reduction - does that 
make it archivally bad ? If you've used it, please let me know what's 
bad/good (other than price) about this product.

thanks,
Frank
