Just my $.02, but I gotta support a couple suggestions:
luvinits suggestion of 1.7 resurrectors or 2.0 boges is right on...strong, full flavor and vapor. A super close second to dripping for many, and actually better for me as you dont get the unavoidable nasty dry hits (unless you really dont pay attention) or the close to dry, semi yuk hits and these are far easier and more convenient than dripping! I tried a bunch of dual coils and they just didnt compare imo.
also have to whole heartedly second skelley...going to variable voltage made vaping SO newly fulfilling and way more enjoyable for me. It opened up flavors, and variations to flavors, and even made some liquids that were 'Eh' great once you found the differences higher or lower voltage made on them. It gives control over not only flavor, but TH, and importantly, whatever carto or atty etc you use. If a cartos getting a bit beat, you can up the power and bam, back to its sweet spot. I could go on and on as to VV...suffice it to say I think that coming back to vaping with a VV device would be a whole new experience this time! And there are so many affordable opts now from box mods, the Ego Booster, Lava/clones etc. And fyi...the Ego batts with a few settings just dont do it for me...not full control w/ just 3.3,3.7 & 4.1v (believe it or not .1 or .2 v variations can make a real difference) and not a high enough range (many people find 4.2 to 4.4 or 4.6 so to be a sweet spot)
Whatever you go with, welcome back and enjoy!
PS: If you try the Ego Visions I
strongly recommend you clean them first
very, very well! I found a gnarly taste from the plastic or the primer fluid. I suspect both actually. First one I even ran 3 fills through and it didnt go away. I tried another out of the wrapper and same thing. Better when I flushed it out first, but still there. A flush, an overnight soak in vodka, and a flush and dry did the trick...way better.
OK, so maybe it was more like $.04!

Sorry so long winded...
