I really don't have a ton of experience on the pulps either, but just trying to relay my experience with them, and advice from others when I do them too.
When I say liner, usually mean blankstock. The other kind I always refer to it as bridging liner. The thick non-woven stuff is one of them that I will prime with Gardz if needed. I'm using htis stuff to smooth out the hanging surface, not trying to wick away moisture and creating a "soft" look for the pulp.
I personally don't like 880 for anything, so rarely ever use it. I have heard many examples of 880 staining pulps due to its oily feel, and massive open time.
