You'll get a broad range of tips, partly because the style is pretty broad. E.g. If you go to Oktoberfest, you'll find the beer is much more pils-like and less malty than U.S. versions. In fact, there's no resemblance. Personally, I'd suggest starting with 50-70% pilsner malt, with the rest being Munich and Vienna. There's really no place for crystal malt, but you can do 0.25 lbs if you just love the stuff. Then if this isn't "malty" enough, you can reduce the Pilsner next time. Too malty is a real turnoff, and that's why I suggest starting low.
