pinion bearing preload question

I setting up a crushsleeve eliminator and want to know how many inch pounds if drag is good. The pinion seal is not installed so will not affect the reading. My factory service manual calls for 20-25 but I am assuming that is with the seal installed. You members that build rears, what do you set your prelaod at? I am leaning more to like 10 inch pounds but want experienced input. Thanks.
