Gordon,
After reading about your preference for the Ayinger yeast for various German beers (particularly malt-focused Bavarian varieties), I'm going to use it for the first time in a helles tomorrow. Very much looking forward to tasting the results. Previously, I've used 2206, which is what I used in my Maibock (above). I really like that yeast, but if I could get just a little more malt bump from WLP833, I'll be pleased.
