We spend a lot of time on APUG discussing different manufacturers surfaces and it is difficult for the person inquiring to reach a conclusion. The best description possible on the net is wholly inadequate compared to seeing and feeling the paper.
Manufacturers produce sample books for dealers to show to customers but unless you can get to a dealer in person this doesn't help. Might be a good idea if manufacturers would be prepared to send samples books to customers for a price or alternatively send enough samples to dealers who could send to customers for a charge and then deduct the charge on the first order provided the sample book was returned.
Just a thought
