Oh, yeah, that's right; Been a while since page #1, I kinda spaced that out...
Will you have a straight shot, where you could go Class A all the way up? You can get this in colors...supposed to be the best Class A chimney available: (broken link removed) Or you could use rigid liner but you should insulate it. I have an insulated heavy-duty flex liner, HomeSaver RoundFlex. Olympia also makes an HD flex liner.
As far as the height, you could add extra pipe to the top, if it wouldn't look too goofy from the street. I don't know about the PH, but guys have run the Fireview on 13' of chimney with no problem.
