I would go with a 21700 over an 18650 any day, especially when it comes to the DNA 75C. They allow , while simultaneously compensating for the 85% efficiency rating of the 75C. Samsung 30T's or 40T's are my recommendation. If you can provide more information as to how you vape (resistance, wattage/voltage, builds, etc...), I could definitely be of more help.
Hey, I just picked up an Aromamizer (the 3ml version) lastnight. I set it up and I love it, but I keep noticing that the tank is getting hot. Here's what I'm running:
Dual Vertical Coils
Made with 7 wraps of 24gauge Kanthal A-1 on a 3mm inner diameter
Reading 0.3 Ohms
Firing at 40 Watts
on my SMY SDNA 200
The wicking's keeping up great, but the whole tank just seems to get hot after a bit. Any thoughts?
Also any recommendations on how to set up for an Ni200 build? (I prefer 28gauge, for Ni200.)
Thanks in advance for any input.

As far as Ni200 goes, I've had all my success with 28gauge single coils on a 3mm inner diameter. However, I still need to dial in my settings on my DNA 200 some more, before I'm totally satisfied with the results.
