LOL Denny hates the S-23. I've used it a number of times with (what I consider to be) good results, including BOS for a boh pils in a comp with over 350 entries. Having said that, my favourite strain is W-34/70 (though I'm about to use 1450 for the first time

).
There's no such thing as a noble style pilsner.
If you can ferment quite cool (48 or lower) then I like 34/70. S-23, if you pitch enough (1.5 million cells per ml per degree Plato), will handle the cold (48-ish), but not like 34/70. S-23 should be warmed up once the krausen falls to help it finish off strong IMO.
If you are going to ferment warm (low to high 50s) then S-23 should be okay. I've gone both cold and warm with it and had decent results, at least IMO.
Good luck!
