12" stainless butterfly? She's a rare animal and might cost as much as the still, totally unnecessary too.
You don't need a fancy lyne on a stripping still, you need a port and piping to safely take vapor to the product condenser. What I mean by safely is that there should be no risk that you would foam, puke, and plug the vapor piping or product condenser - so taking from the highest point, and if there isn't one, making a highest point (8" spool, 10" spool, welded ferrule on the tun).
If you have a vapor tight tank, you are good to go, if not, it's probably cheaper to covert a dairy tank like the captain says.
