re: Homebrewing: In-Process Thread

Question, somewhat related. Using that massive amount of hops, i know some here, as well as this guy, does not filter out the trub when he brews. This beer would undoubtedly produce massive amounts of trub. My question would be, wouldn't you lose some volume due to trub loss when racking to keg/bottle after all said and done, as opposed to straining the hops before the primary? Or is the loss negligable to the exposure to wort the hop slurry gives to the primary wort?

Also, has this guy done any experiments with using muslin bags vs. straight pitch of hops into the wort? Curious if there is a noticeable difference.
