For my all day setup I was using an MVP but just upgraded to an Eleaf istick. I run a protank 2 on it. I know there are better tanks but this tank never let's me down and my coils usually last about a month using 1.5 ohm. Probably the best tank right now is the Nautilus bvc.
I have recently acquired a tug boat hex ohm 50 watt that has really taken over throughout the day. It has a tug boat rda and is built at .3 ohm. Great flavor and hit. Much better than any tank out there like most drippers.
For clouds i have an authentic brass monkee. I run it at .12 ohm with 24ga parallel 5 wrap. This mod is a beast! Monster clouds.
I would also recommend skipping the starter kits and start off with variable wattage. This will allow you to get a bigger hit without having to work so hard for it. MVP is a great mod but the istick is much smaller and is adjustable to 20 watts.
As far as wire for rebuilding, I prefer kanthol. Ni chrome ramps up to slow for me. I hadn't tried g plat yet but have heard good things.
