I am the proud owner of an Atlantis. But I can't use it to it's full potential, I have an SVD 2.0 that can scratch the surface, and a Nemesis clone with a couple Sony vtc 5 (got lucky with a trusted vape shop) that fire it well enough, but I want to take it further. I think I'm aiming for a 50w box mod. I know my budget is going to be $150 with a $50 push if I find something I have to own. I'm thinking either the ipv 2 or sigelei 50w, or maybe even pushing those to the newer model. I'm really not sure here. I have a pair of MVP 2.0 and like them so I'm kinda leaning toward the ipv because they "seem" similar in my mind. Any other suggestions I should look at? Any huge pros or cons to either? Thanks, Cheers!!!
