I am planning on bringing a few samples to my clubs meeting this weekend for just that reason, but thought I would throw it out here as well.
One was a Marzen, Jamil's recipe from Brewing Classic Styles, one was the Can You Brew It Arrogant Bastard Clone, and one was a Celis Pale Bock clone from Austin Homebrew. In the mix as well I brewed my Pale Ale recipe, with no problems, and my Hefeweizen with no problem.
I do pitch the whole starter. I thought about decanting, but I thought part of the idea of a starter was to pitch active yeast and thought cold crashing would negate that, but I guess I could crash, decant and then maybe add a bit of wort in on the brew day to get it active again.
