lolol! Well you won't know what you like until you try a few things so... You can always save the sucky cartos for emergency backup

When you get the atomizer plan to soak it in Vodka or Everclear every so often and blow out the alcohol.. add juice and start vaping. I do mine about once every 4 days or so. Some folks that vape dark, sweet or VG heavy juices might do more often. The cleaning will help them last longer.
Glad Sayer pointed you towards an atty. You won't know until you try if they are for you. If you hate it, it goes in emergency backup pile but...I doubt you will.
