Congratulations and welcome.
All good recommendations. Also, be aware that some of the 306 drip tips can come off while being carried in pockets, bags, or purses. Best starter DT, for 306, is the clear Cherry Vape Canon. You will be able to see the juice level while you are fine tuning squonking.
DH travels out of town to work via airlines twice weekly. All last year he used cartos on REO Mini, in shirt pocket or carry-on, and never had a leaking incidents no matter the amount of juice in bottle. He did have a few minor leaks, with change of altitude, and a few other times using attys.
The clear, plastic cartos are pretty cool looking but as said above they are quite fragile and you will have a tube come off at some point while carrying it in your pocket. Sometimes that doesn't break the wires to coils but sometimes it does. Also you will not be able to pull Mini out of pocket using atty if you use the clearos.
The shorty cartos take "stealth" to the extreme.
