Sweet! I might try them in some sort of blonde ale. I just ordered some wild harvested lager yeast from craft cultures at ebrewsupply and other Michigan hops. I'll be set for a while.
Good advice about not making your first batch harder. A 36 qt bayou classic is $34 at amazon. While I think the 44qt is better for 5g batches you could definitely make it work. The Pliney kit can't be cheap. So don't waste that, I think you'll be disappointed. Maybe go to the LHBS and pick...
I recall going 3-4 generations with no problems. I used to make larger starters and throw some into mason jars so I'd have a "clean" culture vs a slurry. I'd store it for extended periods and make another starter when needed.
I just ordered the bohemian pilsner and helles lager Palmer kits from AHS. It may be a few months before I report back. It was like 43 total for both kits and they were extra to my original order so didn't cost more shipping.
Best kits I recall making were Williams brewing California pilsner...
I'm no expert but I personally would have waited for the bells yeast to take hold before adding the hefe slurry. Culturing from bottles takes a while to build up. Do you still have the 3 other Oberon bottles?
