This is going to sound weird, but my impression after brewing a few different lagers with a sack of Rahr North Star Pils, is that I preferred it when blended with some Proximity Pale Ale malt (the two row that I happened to have on hand). On its own, the NS Pils seemed a bit too rich for a straight Pilsner or Helles. Maybe that descriptor is not apt here - but I can't pinpoint the word choice to describe the flavors I perceived when Rahr North Star Pils was used solo or in combination with just a touch of Carahell for a Helles.
Definitely give it a go, as you may really like the richness from it, but I prefer the Weyermann Barke Pils, if going with a straight pilsner malt based beer.
I think that I simply prefer the slight graininess that I get when balancing the lager beers with both a pale 2 row and Rahr North Star Pils in the grist.
Or I could just be fooling myself (known to happen!)
