I bought the zenith from a collector its far better then the patriot and yep it will hold the air adjustment. The top screws down onto the ring to lock it in place, the zenith hits like a truck on my Panzer and its IMO due to the welded neg. posts on the unit. On my DNA30 it hits damn close, but the vape isn't as hot as it is on the panzer. I do like my Patriot, but its just not what I expected it to be, I hate drilling out post holes and its a must for the patriot if your doing something like the duel parallel in 24g. The post holes on the zenith though will support such a build without any mod. The biggest reason I like the zenith is the flavor it produces there is something about that atomizer the way its made, I honestly think a slinky build would taste good in it.
