Hi,
Is there any benefit to mash efficiency, temps throughout the MT, better/less grain bed channeling, or any other reason to have a manifold with a lot of holes ie nozzled, loc line type wort return to gently disperse the water evenly over the grain bed, under the wort level of course VS a sweeping bend or maybe 2 out of center tee fitting that recirculates around the outside of the MT .. sort of a mini gentle whirlpool over the grain?

thanks haeffnkr

I think there some benefits, most of what you list. Most may be hard to quantify.  For me, a mash return manifold helped my mash temps converge and stabilize more quickly. I'm using this product and found it to be a decent value, easy to clean, have robust construction.

I simply use a tube that returns recirculated wort in one end of the mash tun (thru the lid and just under the liquid level) that I draw from the opposite end thru a ball valve.

I am looking at this manifold as well.
Does this or similar manifold help clear the wort faster with a dispersed flow that filters with less disturbance to the grain bed? ( making some assumptions here )

I use locline with good results:
