Right now I have one, a Mutation X v4. I keep having this urge to buy another one like a Goon, a Recoil or a Tsunami. But I have to ask myself why? I hardly ever use the one I've got and I find dripping to be somewhat of an inconvenience and messy at times. I like my big tanks because I don't have to refill them very often. Basically I am lazy. So I've got four RTAs, two RDTAs and a dripper. So I can say I have a dripper, should I just be done with it at that?
