Hulls look about right, I guess.
Based on response here, I mashed with entire bag of grain (yes, ground at the HBS). Result for me was okay. I got stuck a couple of times fly-sparging, but cleared it only by increasing the flow a little. My OG was spot on (1.061) the expected.
The only out-of-ordinary thing is that I had a lot more clearing to do in the funnel to carboy process. Also, the "stuff" on top (krausen?) of the wort is like a coffee-colored meringue on top of a pie. Never seen the look of this, but I've never brewed with Munich malt before either. Looks like it is already starting to drop, though. The trub at the bottom is already nearly an inch thick. If I don't secondary, it is going to be interesting trying to siphon without picking all this up - if the top adds to the bottom trub. Wheeee.....
