A lot of us when we started went with tobacco flavored juices. I would try and stare with either a pipe tobacco flavor or something called RY4 both are fairly easy to Find and very common; every vendor will have different versions. In fact if you have a vale shop near you; they will usually let you taste their juices and help you find something more "you." Youay want to pick up another CE4 tank if you are liking those or try a different type. Usually people find that the bottom coil tanks give a slightly better flavor.
It's all trial and error till you find what you like. But the journey is most of the fun!!
Congrats on making the switch and best of luck!!!
