I see the Moen Brecklyn specifically shows PEX as an allowable option, including (if I read this right) from mixing-valve-to-spout.

What is the difference between this model and the Moen models Terry names above? (Sounds like PEX isn't the best choice in any case....)
look at the instructions it doesn't say to use PEX to the spout and the pictures show copper. Personally I've only plumbed it right , but I'd love to hear how it works by running PEX, you might want to test it before you tile the wall, otherwise you might be opening walls to fix
