I was wanting to know this myself... I don't really care for the bottom coil clearomizers because the vape doesn't seem as flavorful or warm versus top coil. The 30s would be the perfect tank for me if it came in glass. I don't even vape tank busting juices, but I just love the aestetics and feel of a glass/steel tank. If they came out with a glass 30s I would gladly pay what I paid for my aero protank for the iclear 30s. The plastic tank totally makes it feel cheap imho.
