My experience with an RBA is limited to a couple of AGA-T2 RBA tanks. I have used them on my mechanical Silver Bullet and my two Provari's, and actually prefer them on the Provari's. I prefer a cooler vape, and never was able to get a satisfactory vape with any coils that I made at 1.0 or higher on the Silver Bullet, and I won't do sub ohm. I found a sweet spot making a 2.0 ohm coil for the Provari's. I use 6 - 7 wraps of 30g kanthal, and always check the resistance with the Provari. I've only used stainless steel mesh wicks.
I suggest looking into
Micro Coils.
As long as you stay above 0.8 ohm with your AW I8650 IMRs you should be fine. These batteries have a 10 amp continuous discharge rate. Lower ohms than 0.8 you will need one of the IMR batteries that have a 20 amp continuous discharge rate.

Make certain you know how to figure the amp draw from your battery with the resistance coil you make by using this
Ohm's Law Calculator. Expect to see the battery time you are used to be cut nearly in half when using your Rebuildable, they pull that much more amps from your battery from normal juice attachments.
I wouldn't even bother using your 18350 AW's with a rebuildable as they only have a 6.0 amp continuous discharge rate. You won't be able to go much lower than 1.0 ohm with these batteries and still have a little wiggle room for safety. Even with > 1.0 ohms, battery time likely will be very disappointing.
