Way to jump in with the $$$$ right off the bat
first off I would read the diy eliquid forum from front to back and then sideways - 100% vg juice is going to be really thick, hard on to wick in clearos, but will give massive vapor but makes the throat hit and flavor very muted
did you order atomizers to go with the atomizer cartridges you mentioned (cartridges usually just have a little bit of foam to hold 5-10 drops of eliquid - cartomizers will hold 20-25 drops - clearomizer will hold .9 to 2+ ml (about 35 drops of pg/vg blend liquid - 100% vg is about 25 drops per ml)
Protank and evod are the new big thing (I like mine anyway) in tanks and clearos and have interchangeable atomizer heads
DIY nic liquid in strong strengths (48 to 100 mg) is extremely dangerous to you, kids, pets, and anyone else that may come into contact with it (100 mg can and will kill an adult if spilled on skin and not cleaned off right away - as in within a minute - if a child drinks it, it would be bad, very, very bad) not trying to scare you, well, yes, yes I am trying to scare you - but you would be best ordering a 24 -36 mg unflavored nic juice and diluting down from there until you know how to handle it
I am sure more experienced vapors will be chiming in shortly with more and better advice
welcome to ECF and good luck with quitting the analogs
