Adding cocoa nibs to milk Stout soon how much

Hey everyone.

I’m getting ready to keg the  milk Stout 5.5 fermenter but obviously 5 gallons into keg

I’m planning to add .75lbs (slightly lower than 1lb)  lactose at kegging…Shouldn I go 1lb??

I’m thinking of adding cocoa nibs to the fermenter before I rack it…
What’s the dosage rate cocoa nibs,  and how long…??  Is it worth it??  But I’ve heard/ read that. Chocalte extract is best…

Coca nibs str8 to the fermenter in a muslin bag with string…I’m 2 weeks now into the fermentation this Friday and at  F.G now/  71 F rest temp for a week current… since I’m unavailable to cold crash at moment…I will cold crash by Wednesday or Friday of this week and then keg after the few days at cold temps…

I saw some of the posting with hatred for lactose…  Cmon what did lactose do to you…lo… Actually I’m not in very sweet beers…  But I do like young s double choc. Milk Stout…occasionally…

Actually trying to make the man’s milk from Noble Ale works…

I think my Wort flavor is killer good…so I don’t want to mess it up with too much lactose and flavors from the nibs…

My rant is done…
