Using wheat flour in the mash?

[Pennine]

Anyone try using wheat flour in a mash? Any tips on how to use it? I have read to boil and just directly mix with the malts? I was thinking about mashing for 30 min with only malt and then adding the flour for the next 30 min to help prevent a very thick mess.

I have limited space in the braumeister and wanted to get a 6-7% hazy lager to use up some of these fruity hope I got on a discount. I also have a 3470 yeast cake that is ready to go.

The first stout I did was with wheat flour for extra body - I mixed it with cold water first.
Just to note this was an extract brew so I added it to my hop mix.
