My suggestion is try cartomizers too.
If nothing else they will be a great backup if you ever have atomizer problems. I recommend learning on Boge 3 ohm and then try the hotter Boge 2 ohm ones. Those are the most popular cartos on 510-threaded devices. I use thin juices (20% or less VG) for longest good performance out of a carto and I avoid juices that drop a lot of flavoring sediment in the stuffing. You want to get 18 to 24 drops into a Boge, clean it up, then lay on different sides for 15-20 minutes to make sure every bit of stuffing gets dampened. Then vape. While vaping keep it damp (add juice if the vapor seems dry or off-flavor even slightly or if the carto is getting unusually warm - you don't want to singe them because that adds a bitter taste (which isn't too bad with tobacco but ruins sweet flavors). I use a plastic or delrin 510 drip tip instead on the endcap - easy to remove to look in so I also check that way, especially before putting it on a fresh battery or leaving the house - if the stuffing has gone white on top it could probably use more juice. I can get 10+ days use out of a Boge. Actually over 2 weeks on my current one (which is 4 weeks for me because I vape it 1/2 the time so I count that as 2 weeks)
There are alot more exotic cartos but those are simple and popular.
Another flavor that is real nice in tobacco is peach. On another theme, vanilla and/or light caramel like FreedomSMokeUSA's oRYental 4 (a sweet RY4) is an interesting addition to a normal tobacco juice. And for another - FreedomSMokeUSA Orange Ball (chocolate orange ball) - the chocolate adds body to the tobacco and the orange adds highlights. FreedomSMoke USA also has so many tobacco flavors (though the specialties are 50/50 so thicker than most use in cartos or tanks - I like to drip 50/50 juices)
Speaking of dripping - a normal 510 atomizer and drip tip provides an easy way to test juices and vape thick ones.
And learn to clean your atomizers before you have problems. I don't use tanks but make sure you have a spare tank atomizer and find out about keeping them clean.
