Hello, I'm not new to vaping, but it has been quite some time since I vaped. I've been a smoker most of my adult life and I'm now to the point I seriously want to quit. My plan is to use nicotine patches and vape zero nicotine juice to help with the "drag" habit (plus I like the taste). My last vape unit was a eleaf istick with a kanger tank. The eleaf eventually died and I hated the tank because it was messy and leaked a lot. Anyway, since I've been out of vaping for so long I've not kept up with the technology and all the various tanks and such that are available now. I've tried to do some reading and watch videos, but it's a bit overwhelming these days. I think at this point I want an Aegis X mod (I like the size and the big screen, my old eyes don't see the small screens too well), but I have no idea what tank to get. I do have a few requirements and I'm hoping someone can make a recommendation. 1. I'm not looking to exhale Mount Vesuvius volumes of vape, I'm mostly interested in good flavor. 2. I don't want a tank that I have to run at high wattage, preferably 50 watts or less. 3. I want one with available prebuilt coils that are easy to change, I don't want to have to sit and build coils. 4. It must NOT leak! 5. I'd like a generous amount of liquid volume (5-6ml) 6. It must be easy to fill. Any recommendations?
