Lager yeast can be different for sure. I have done the same with several over the years, and have settled on a couple favorites. I use WLP-830 for more hop forward lagers, and WLP-833 for malty lagers.
I've reached the same kind of conclusion, although for me it's WY2124 and WY2206.
Many say that WLP-830=Wyeast 2124=34/70, so we agree on that one.
I can't say why, but I grab WL yeast at the LHBS for lagers.
I love 34/70, one of the best dry yeasts on the market. I do really like wlp833, but don't make the effort to use liquid enough now that I'm brewing 6 gallon batches.
Denny, is the 2206 supposed be the same or similar to the 833?
