Hi, Matt!
I find - a lot of guys will disagree - the TFV12 to be a great atty, but, in my experience, use the quadcoils and keep it around 50-60W. Reasonable clouds and battery life; I'veen using the 12 coil for a couple of weeks and yes, the clouds are astounding, but also are the batt consumption and the heat - even with a heat sink installed, it's uneasy to handle, and I don't want to think what all that heat is doing to the electronics.
Just my 0.02
