Howdy! and Welcome 
+1 on suggestions for lower nic level in the Kanger - sub ohm coils tend to produce more vapor and pack a bigger nic wallop - had to cut from 12mg to 6mg when I switched to sub ohm vaping... sometimes, if I am chain vaping on a .2 ohm, .3 ohm build, I will use a 3mg juice as even the 6mg at that point can make me a little goofy(er)
and congrats for making the switch!
