Moderator 30mm or 40mm?

Huma takes the cake. It's super light (in 30mm), super effective, and adjustable. I've got 4 of them and another one in 40mm if that tells you anything. 



Simply for this reason... If you find you can use less moderator, you can simply make it shorter. The one in my fx crown is under 4" and is silly quiet because of some mods I did to the shroud behind the moderator. 

If you need more, add more. It is either equally or slightly more effective than any of its competition, while also being extremely light. I don't know why anyone would get anything else to be honest.
