I'm currently using 2 istick 30w one with nautilus mini and other is innokin apex, what would be a good step up from what I have. Power is not to much of an issue as I don't go above 25w
Tbh I looking at something totally new as I like to have a change. I will definitely be getting a bigger tank 2ml just isn't large enough for MeHmm... SO many options. I guess I would have to ask what you hope to achieve, and what your budget is? If you want something exquisite looking, small, durable and feminine, the XVO would be a nice choice. Temperature control has it's benefits for many. For single battery, compact, I really like the Evic VTC Mini best of all the small T.C. mods I have. If you want a true road warrior that you can run over several times with a large truck and it will continue working without fail, Provape probably holds the crown in that category. They just introduced a new 50w successor to their mighty P3 line. They are sleek, outrageously well built, and American made, but pricey.
Whole other genres are squonkers like the Reo line, which carry a juice bottle and are very effective with bottom fed rebuildable drip atomizers that support the bottom feed mode. I could go on for hours..
What aspect of your present gear do you want to find more satisfaction with?
Pre built as I haven't got clue where to start with RTA, I'm a bit of a thicko when it comes to any techDo you want to stay with pre built coils or do you have the inclination to get into an RTA?
Flavour is a biggie for me but enjoy seeing them cloudsWell, then you really have a lot to choose from. What is most important to you, flavor or vapor production. We need more of that info to give a tank recommendation. For a mod, the step up would be a device with a removable battery. IPV D2 and D3's are quite cheap now, have temp control and are easy to come by.
I have both of those devices and it doesn't get any simpler to use then these. IMHO
