I've got the same 30 degree EE and the first night was 27 degrees and I was plenty warm on a BA Air Core. I toss and turn and for me I don't end up feeling like a twisted up tootsie roll. You do need something for your head and a merino beanie worked well. Never had any problems with draft/air. Packs to the size of a football and weighs 1.6#. Very pleased with it.
