Forgive me for asking, but using a lager yeast would make your beer a lager, not an ale, right?
How about this...just use Wyeast 1056. It is clean and versatile. 1056 will ferment at both cool temps and warm temps. A local brewery used it to ferment their "lager" style beers, using cool temps. The temp is from 60F to 72F. And I think it will work at even more extreme temps.
Or, use the Wyeast 2112, California Common strain. It does well at warmer temps, 58 - 68F.
With regards to the above comments on W-34/70, we will keg some very soon, and a full report will be posted. Based on my small sample taste test, we have a winner!
