hey pikestr28 I have a mvp 2.0 energy series and its a great mod. its got VV 3.4 - 5.0 and 6.0 - 11.0 for VW. I don't use it much but its got that output charger on it; but I do use the pass through charging. that's why I bought unlike those ego style batteries where you have to charge it rom the top. for a go to tank for it though I would go with the nautilus 5ml tank that's what I use, and I have now trouble with it at all. you can use either 1.6 or 1.8 ohm coils, the same with bvc and bdc. I use the aerotank v1 with my mech using .8 to 1.5 ohm coils. the MVP also has some other useful features like ohm reader built-in, protection for faulty tanks, easy type buttons, and ego to 510 threads.
