Acceptable Sub for Continental Pilsner Malt?

Canada Malting Superior Pilsener is very good; not quite German, but close; I was impressed the first time I tried it last year (their pale ale malt isn't shabby either).

 

If you aren't trying to exactly follow a pilsner recipe, I think NA 2-row should be sufficiently pale so as not to make it dramatically different, although there may be flavor notes that will change, too. Especially with a different yeast.

I don't think it would be bad at all, but it does sound like you are well into the territory of "making the recipe your own"...which ultimately requires some trial and error.

 

By the way, if you Google: "srm pilsner malt vs north american 2-row", you will find a discussion on another forum where somebody speculates that his pilsner might come out the right color if he uses pilsner malt instead of Marris Otter. And somebody else complains his witbier looks like piss because of the darker color malt.
