Lots of rice hulls! I typically use a pound of them in a wheat beer for a 5 gallon batch.
Stuck sparges aren't as big of a deal as getting a decent crush on my wheat malt. I usually take extra care to condition the barley malt portion, and crush a little coarser than usual to leave the husks as intact as possible. I then have to run the wheat malt through my mill 3 times to get a decent crush. I get about 10% lower efficiency when using a large amount of wheat. If I crush finer to get better efficiency, then I run into slow/stuck sparge issues.
The wheat malt I have is also pretty high in protein and glucans, and is undermodified, so I need to at least do step mashes, and sometimes decoction mashes to get the wort flowing well. It's not a big deal, but it adds a couple hours to the brew day, and leaves me wondering why I don't just buy some malt extract.
