I know this question was to someone else, but thought I would add in about SS.
Ok you like big clouds but also higher resistance builds-again the TFV4 makes coils that are levelling on stupidity cloud wise, and others that are as high as 1.5 Ohms single coil.
I don't own the IPV4S, but do own 15 regulated mods, most TC, but SS coils are OKish-even on my DNA 200's with profiles from Evolv themselves though they never seem to work as smoothly as NI200 or TI, so much so that I am not using it for TC builds just yet. I am sticking to TI for the foreseeable future.
The good thing about it is being able to use it in both power AND TC mode, but you need a mod that does SS to do so properly.
If you want a tank kit, by kit I assume you mean full kit? I would say you already have one of the best if you use the Clapton (Single coil) RDA that is included, or purchase the dual coil RBA for it which I use with it.
Other tanks that are great are-the freemax stare Pro(probably my most recommended if you DON'T want to rebuild and use standard coils), the Crius is one of my favourites, but it is fully rebuildable, no stock coils I'm afraid, and the Uwell crown most people love, and the NI200 coils work great with it. There are more I rate highly, but they are fully rebuildable (aromamizer ETC.).
I think you already HAVE the tank you are looking for-its just the stock coils it comes with I don't think are the best choice-they make about 10 different coils for that actual tank. The two included are juice drinkers, and the RBA is a single coil one (That works good though, I either use that or the dual coil one, the dual coil one will satisfy your cloud desires well
