IMHO Andria ideal flavor range(I'm the same way) is anywhere between .8 and 1.2ohms. I use mesh though. I've found you don't have to go nearly as low ohms with mesh for a fantastic flavorful vape. I found myself with cotton(after someone(baby mama)threw my mesh out and until I got more) continually building lower and lower ohm coils. I use mechanicals and just got a magma as well. It's a LOT of atomizer for a single coil build. Did a quick dual with cotton. Not enough experience with it to say this or that. Sorry. Nice vape though.
Hate to be that guy but, get something that fires below 1.3ohms. Especially if you're rebuilding. The I leaf 30w is a good choice. It will allow for a much wider range of builds with thicker longer lasting gauge wire. Fires to .45ohms I believe. Had the same 1.3ohm cutoff when I started so I know there's a lot of limitations with that cutoff. Plus, now you could do dual coils if you chose to. Dual with a 1.3ohm cutoff is tough...
I really don't think my asthma will allow me to vape that way; too much or too thick or too hot vapor either gives me a coughing fit, an asthma attack, or both. I do have a mech, but the coil I use on it is 1.3Ω. And I FARRRRRRRRRRRR prefer to make adjustments to the vape quality "on the fly," by adjusting the wattage, depending on how my asthma is, at any given moment.
Asthmatics can't vape the same way as those with normal, even smoke-damaged lungs; the lung capacity and resilience just isn't there, but what is there is a hair-trigger sensitivity to anything which even slightly irritates or narrows the airways.
