Thanks for all the replies. I might have had a little to drink making this
thread forgetting that I made it.
I ended up buying a Mutation X V2 clone, wire and cotton.
The leaking is coming from the top and bottom of the ring that allows you to adjust the airflow. Generally when you push it up and down slightly you can see it being squeezed out.
I've used horizontal, vertical and the rebuildable, had leaking issue with all of them. I am in Minnesota so we do have some pretty volatile temperature changes. It's August right now and I can see my breath outside, but can be 85f the next day.
The leaking is at it worse when I put it in my pocket and take it to work with me. At home it may leak a tiny bit but that's not an issue.
