Hi guys. I always ask questions here cos your really helpful. It seems my last question about heavy lung will be resolved when I don't drip all day every day. Because of this, it seems I need an rta and get back to some mouth to lung hits. I have a few (subtank, lemo, etc...), but they all have glass tanks and I need something stronger for when I'm at the pub (bar), or just out and about. I need something cheaper than an expensive kayfun. Is their anything cheap you would recommend or is delta II my best bet? Thanks guys
