Why vorlauf? What is the advantage? Won't any debris from the mash just settle out in the kettle or even more so in the fermenter? I'm batch sparging if it makes a difference.
In a decoction, husks are thoroughly boiled. So I doubt that's a major concern here. I think clarity is probably the biggest reason, but you're right - just let that stuff settle out as the beer cools and ages.

How do these BIAB guys get away with what they do. It's not like they can vorlauf. So is it really essential?
Fine mesh bag captures those small particles of grain.
So why not put a mesh bag over your manifold and skip the vorlauf? I'm just asking.
This is no different at all. There is a ton of sugar in the wort to buffer the grains.It's actually a little different. Given that the husks have the wort sugars to buffer them in the decoction, they don't leech tanins as they would without the sugars. That's one reason why fly spargers monitor the gravity; once the amount of sugars drop, you risk leeching tanins around 170*. But with the sugars, you can certainly boil the grain without any astringency.
