Digital BW, The Print

I'm curious if anyone has used the Ilford 10x12 Smooth Pearl
Pre-Mounted Boards:

I'm putting together a post-bound book of prints and would like paper
heavier than the 
standard ISP. I don't have either the equipment or space to do any
type of mounting in my 
apartment.

On another note:

I've been playing with Carl Schoefield's "Carbon" IJC/OPM profile for
Ilford ISP and the 
prints are gorgeous. Thanks Carl!

And yet another note:

I had posted a request for info on albums a few weeks ago and decided
to get two of 
these:

One will have ISP and the other Condor B/W. Dick Blick also carries
the same for slightly 
less money.
