Yikes. You need to look into batteries first before you even think of running a build like that again. Lol. Your Panasonic has nowhere near the amps required to run anything but high ohm builds. Harsh throat hit will be the least of your problems....
And for the record, if flavor is what you're chasing after, then you're doing it wrong. I can only imagine a build like that will be very low ohms. When you go that low in ohms, pushing that many watts, you're just cooking the juice and the flavor. That high of temperature decimates the flavor, and of course ends up being more harsh.
You don't need to build super low to get good flavor. Huge misconception.
