This is what i just whipped up.

The first version i would likely run it without any spices.
i think that i will mash in at 149(my standard temp) to limit the overall variables.
i think that i will need to add the beta glucanase to have a prayer of getting water to flow through this along with lots of ricehulls.
fermentation temp wise i would think that 72 would be a safe bet?(temp range is 61-75 from apex). 80% attenuation seems like a safe number(they call out 78-82%)
thoughts? I am a long way from brewing this as i dont have the ingredients on hand and honestly this is a summer beer. I would want it to move quickly.
I would remove the oats and flaked wheat. Use about 45% wheat, 30% light munich and around 13% vienna. You need 2-3% (max) melanoidin, since I know you cant do a decoction. And the remainder rice hulls. It works best at around 5.5%, or a bit lower.
The glucanase might help, but the rice hulls are always spot on. Both?
Even more important is the right yeast, as that’s critical to the style. The Apex Hefe is fine.
MOST CRITICAL is to underpitch or AT MOST proper pitch, as an overpitch will almost completely prevent the phenolics that give a good Hefe its character. I know that over pitching is part of your religion, but you’re gonna have to restrain yourself for this one if you want it to come out great.
Ferment near the warm end of the range, like 68, and raise it 4-6F on day 3, it’ll be ready for kegging in 6-7 days.
Can you do a step mash? If so, 105 for 25, 145 for 30, and 158 (!) for 35. If that’s not a thing (makes for a long brew day…), use a single mash at 152-154 to keep enough of the sweetness. 149 will
not be your friend.
My references for the style are Franziskaner and Weihenstefaner. Paulaner is much less of a beer.
Since you have time - for me this is also a winter beer! - wait for the right ingredients and your schedule the extra time in the fermenter. And you don’t need spices if you do it properly.
As for yeast clarification: sorry, you have to shake the keg, but only every 2 weeks. Two or three side tilts does it. It will never fully clear, but it is slow enough to drop that it is manageable.
