I know that the pro tank and the vivi novas with the metal tubes will hold up to cinnamon juices. Are there any others ? I had gone back to carto tanks for awhile. However i,ve recently tried one of the vision dual coil clearos. I,m really loving it and had forgotten how easy a good clearo can be. Unfortunately im sure if it would fail if i tried to use some juice cinnamon juices in it and am looking for sometihing besides a carto tank handle these flavors.
