I think i read on a FB group that the way to get it to act right on colder than Z7 is to keep it at around 3ft. Thats the only thing that i havent tried. That makes sense because my winter injury is usually past that. I think trim at 3ft or so and get the laterals to push is the key to anything colder than Arkansas.
