Welcome and glad you joined
cjsanders2010. About sub ohm coils:
"So seeing as I now have some good MTL (Mouth to Lung) tanks and repeatable setups at 8-12W, and some nice replicable juices, I thought I’d set up my predominantly DL (Direct Lung inhale) Bellus tank with a DL setup – dual Claptons 26/32G Kanthal (which incidentally took me three goes to get into the Bellus’s small chamber without shorting, details if you’re interested) and try my two current favourite juices – Pina Colada (AM vape), and Mild Sweet Cigar (PM vape) The verdict? Didn’t taste or throat hit ANY better. Sure it produced bigger clouds (subjectively twice as big?), but used 60W instead of 15W, and a directly proportional greater quantity of juice – I normally use about 1 ml/hr in my MTL tanks, this setup used 2ml in half-an-hour.
Bottom line - it appears you don't need mega coils or Watts for good flavor or throat hit. Admittedly it's taken MONTHS to find the right gear etc seeing as most manufacturers are aiming at the DL market (and why wouldn't they? The money is in the consumables...), but with persistence (
/ADHD/OCD) you can replace cigarettes on the cheap... Happy to share what I've learned so far..."
The above was copied from another vaper who has made a point and tells the whole story.
its killing the back of my throat

I believed that Wayne failed to mention in DIYorDie vid, is that very few folks can be sensitive to VG which can result in a sore throat. Higher VG and/or lower or different Nic usually fixes the problem.
Note that the Cupti battery will support almost any other RBTA/RDA's provided the coils are setup to shine at 7 or higher watts. If you like the 1.5 ohm coil, stick with the whole set up as is.
