Wire gauge should roughly match coil resistance, so what resistance are you aiming for? If you were to use thick wire in a high resistance build (low power) you would get slow heat up times and if you took it too far the coil might not even get hot enough. Air flow also needs to match power applied. The more power, the more air you need.
I used a Trident with dual coils as my main vape atty for quite a few months before I moved on. If I remember correctly the single hole is quite small, so unless you are prepared to drill out the inner barrel you will not be able to put that much power in there. I assume it's going on a mech mod, correct? What style of coil are you going to use?
