Is it the paper used in the softcover Masterworks?

famac, it is better quality, slightly thicker and some what more glossy but not shiny and it doesn't have too much evident bleed through like the latest soft cover masterworks,
I would say this is as thin as one can go with out having any excessive bleed through and it doesn't look too cheap.

That said I am in favor of thicker paper, this kind of books should look and feel as expensive as they are with out any bleed through
