Congrats on almost a year. Sorry to hear about your issues and your Dad's passing. Cancer has also ravaged my wife's side of the family.
Here's some info:
Different delivery systems:- note
bolded Atty, Carto, etc is the abbreviated form
Atomizer/
Atty- an element on to which 3-4 drops of
juice is dripped- usually used for testing new juices because Attys are easy to clean. There are some diehard Atty users because it’s the best
vape possible but very time consuming.
Cartridge/
Cart- a container with sponge (filled with
juice) that is used with the Atty- juice drips on to Atty from filled cart and is vaporized- older outdated first “tank” system and prone to leaks unless the user is willing to buy extra seals and “fiddle” with them.
Cartomizer/ Carto- metal tube with stuffing and element. Holds anywhere form 1- 4 ml of juice. Carto is fully saturated and must be occasionally refilled when juice runs out. My Cartos last 1-2 weeks. Best Cartomizer I’ve found is the Smok Tech XL 1.7 single coil. Boge 2.0 ohm cartos will give a cooler vape. Always use single coil cartos with 3.3- 3.7 PVs for the best vape.
Carto+Tank- a Carto with a hole punched in it. Carto is than placed in a glass, metal or plastic tank which is filled with juice- juice saturates Carto by way of hole in Carto. My Cartos with a tank last, before tight draw occurs: light juices- 80-90 ml. dark juices- 50-60 ml.
Clearomizer (includes the Stardust and the Vivi Nova Tank)- a plastic or metal tank with a wick and element. Contains NO stuffing. The rebuildable clearos come with heads (coil+ wick) that can be cheaply $2.00) and easily ( 10 secs) replaced. When the head burns out simply unscrew the old head out and screw in new head- takes 10 secs. My Vivi Nova heads are lasting about 8 weeks BUT I wash the heads every few days. I've found the Vivi Nova to give the best draw. After 8 weeks my heads are stilling firing great but the wicks begin to shred.
When I first began vaping I used Boge 2.0 ohm single coil cartos (1 ml). After 1 month I switched to Smok Tech XL 1.7 single coil cartos (1.8 ml). Next I used a carto+and tank (3ml) setup. When the cracking and wicking issues were resolved I got into Startdusts (1.6 ml). I now use the Mini Vivi Nova (2.0 ml) rebuildables as I feel they give a better draw and are far superior in quality. It is VERY important to match the correct ohms delivery device to the PV we are using otherwise, dry hits or a weak vape will occur.
You have to be careful if vaping acidic juices as they will damage the plastic tanks. Some use a carto with the glass
http://www.ibtanked.com/ As noted above (carto+ tank) the cartos must have a hole in them. You can either order pre punched or do it yourself.
There is a new glass “clearomizer” type tank with replaceable coils about to be released. Will wait for the reviews before buying.

Thanks again and thanks to those Vets that shared this info with me
