If you use this thinking, why not use american hops and an english yeast.
I got it to homebrewing years ago so I could make the best possible beer. I also try to make the most accurate styles, If you want to just make beer then go ahead and use 2 row
I agree and disagree. That is the beauty of this hobby/obsession/<insert appropriate title here>.
If your goal is to get as close as possible to cloning SA Noble Pils, then the Internet and the kind brewers at SA have provided enough information on process and ingredients to get you there.
If your goal is to brew a great lager inspired by this particular beer, then you can do that too. I think it's a bit shorter to tell bmantzy to "just make beer" by using 2 row instead of floor malted pilsner. Same goes for using American hops and British yeast. You're not just making beer. You're making YOUR beer, the way you want it, and in all likelihood, something you can't get anywhere else in the world.
For me, the hobby is all about experimentation. Sometimes my experiments have the desired results. Sometimes they don't. Sometimes the end result is "just making beer" (in which case I serve it to my wife's friends). Sometimes the end result is better than what I was trying to clone (in which case I am incredibly pleased).
Just because Jim K. and the boys made this beer a certain way, does not mean that a very close approximation using slightly different ingredients wouldn't be just as good, or even better, than the SA version.
I think the word "clone" when we're talking about these recipes is a bit of a misnomer anyway. Just because you use the exact ingredients in the exact proportions that SA used, you're in no way "cloning" their beer. There are so many variables that we cannot replicate (not the least of which is the fact that we're brewing this 5 and 10 gallons at a time, not in a commercial packaging brewery).
I guess what I'm saying is, if a commercial beer inspires you, learn as much as you can about it, then start brewing. If your goal is to get as close as you can to a copy or clone of that beer, then go for it. If the style and nuance of the beer itself appeals to you, and your ingredients and process dictate that you can get in the same ballpark but not exactly "clone" it, then brew YOUR beer.
Assuming you practiced sound brewing fundamentals, sanitation and fermentation, you'll be happy either way.
