I started using the Boge XLs in my tanks right about the time these issues started popping up. I got 3 boxes of the long-shorts, and the first box was really good. The second box on the other hand, not so much. I've since gone back to the pre-punched single coil 3 ohm Smoktech cartos for my tanks and they've been working well. They do have their occasional issues, but at least the flavor has been consistent so I'll continue to use them until something better comes along.
