>>If I'm not mistaken, what I have here is a pad of 1-ply Bristol made by
Canson in 11 x 14 in size. It's 151 lb,<<
I have never seen this (truely) 1 ply weight in a pad offering. What I have
seen is various 2 ply versions refered to as single ply. I have used the "1
ply" pad version and it is identical except for the added ply makes it more
difficult (but not impossible) to see details on a light box. I suspect
that 151 lb is this same stock.
