Welp, SUCCESS!
I started today with the Avocado 24 first because of the bigger deck. Used a Coil Master Jig, 3.0mm, 9 wraps, dual coil SS316L 28g. I can't believe how easy this is. Of course, I killed my first coils by touching them with the (non-ceramic) tweezers. Lesson learned, the next two done and perfect, 0.51Ω on the TAB, 0.52Ω on the RX200 2/3, 0.54Ω after the tank is mostly emptied. No dry hits, no wicking problems.
On to the Aromamizer Supreme, easy peasy, same build, tested 0.49Ω on the TAB, 0.51Ω on my RX200S. Honestly, not really impressed. The flavor is okay, but nothing to gush over. Again, no wicking problems, no dry hits.
Sweet. Now to load up on RDTAs for the vapocalypse.
Thanks for everyone's help. Looking at trying the Boreas next. Is it out of my league?
