I'm assuming that you are a relatively new vaper. You currently using a high wattage, sub-ohm, direct-to-lung (DTL) setup.
The vast majority of new vapers start out with a MTL (mouth-to-lung), lower wattage, standard ohm setup. Many, but not all, of these vapors may over time advance up to a similar setup like you are using now.
I'm just thinking that perhaps you would be better served by using a different tank (MTL and standard ohm coils). You could continue using the Aegis Legend, but at a much lower wattage setting.
I've used both the Legend and the mesh subohm coils for the Aero tank. My review:
Aegis Legend Kit - Geekvape
I was not particularly happy with the coils used with the Aero tank. I often got that "harsh" vape at the recommended wattage settings; reducing the wattage didn't help a whole lot. I would have been happier had there been a coil option for vapers who vape between 20 - 30 watts. I've been vaping at 30 watts for years now and choose my coils accordingly.
