Love these rba tanks. Only annoyance I have is having to pay attention to keep them more or less upright when not in use. I carry at least 4 with me on my daily travels, and am trying to come up with a cap or condom type thing to slap on them so I can just put them in my carry case like I do with carto tanks.
I'm thinking something that can just be slid on over the top cap to cover the drip tip and air-holes.
