Doc, S-189 has acquired a bit of a following as you can do a pretty acceptable lager style beer using it at ale temperatures, so it's a good option for home brewers who don't have the fridge space for traditionally brewed lagers.
I've tasted lagers from a commercial micro using the yeast at 19 degrees and whilst they were clean and drinkable they didn't shout "Bavaria" nose, complexity and flavour.
Personally I'd run it through at sub 10 degrees as I now have the luxury of a dedicated lager fridge and modified cornies for lagering - keen to pick up a few packets when I can get hold of them.
