Not 20W on the KFL.. say it isn't so!!
Negative. 20 Watts on the Helios. You need a dual coil dripper with really good airflow to push 20+ Watts. I find the KFL is not good beyond the natural range of the ProVari, due to its natural limitations. I suppose you could modify the juice channels and the air flow inlet and make it work...but I think the KFL is perfect for what it is. I DO NOT recommend modifying that atty.
I really haven't a clue. BRB need to check.
Going through CDs now. Waiting on the termite man. Car's loaded. I'm so excited I can't see straight!
