Does anyone know of any 22mm tanks that are short? I own a couple Kayfuns, an Aqua and lord knows what else. What I really want is a pyrex 22mm tank to fit 22mm mods that is short. I often use my kayfuns, aqua or even aerotanks, but find myself wanting a shorter tank that's 22mm for a nice clean fit on 22mm mods. I'm open to all suggestions. Thanks!
